Ludovic
vertical specialistGlobal analysis software for corotating twin screw extrusion process design, optimization, and scale-up.
Geometry-to-run linkage that feeds die features into extrusion simulations without re-parameterizing every change manually.
Ludovic focuses on modeling the flow and thermal profile needed for extrusion development, including residence-time effects and non-linear melt behavior inputs. The workflow supports importing and preparing geometry so that die-related features feed into the simulation run rather than becoming manual approximations. Outputs are organized around engineering quantities used for design decisions, such as pressure and temperature trends along the process.
A key tradeoff is that meaningful results depend on input calibration quality, especially for material behavior and boundary assumptions. Ludovic fits situations where engineering teams need consistent simulation runs to compare configuration changes before committing to toolmaking, such as iterative die or screw parameter studies for profile and sheet processes.
- +CAD-guided geometry preparation reduces manual simplification in die inputs
- +Structured process workflow enables repeated runs for design iteration
- +Simulation outputs align with extrusion decision metrics like pressure and temperature
- +Automation-friendly exports support repeatable engineering reviews
- –Simulation accuracy depends heavily on calibrated material and boundary assumptions
- –Complex cases require careful model setup and verification
- –UI guidance for advanced configuration is limited for first-time modelers

Best for: Fits when engineering teams need repeatable extrusion simulation runs to compare die and screw changes before hardware.
B-SIM
vertical specialistSimulation software for extrusion blow molding, parison programming, and container production.
Die and screw configuration scenario iteration built around rerunnable melt-path engineering comparisons.
B-SIM is best fit when die design studies and screw configuration experiments need to be rerun with controlled input changes. The tool’s engineering loop centers on geometry input, melt-path assumptions, and predicted transport outcomes that can be reviewed per iteration. It is also structured for teams that want consistent modeling assumptions across multiple design variants. The result is faster iteration on hardware parameters than manual spreadsheet-only analysis for the same scenarios.
A key tradeoff is that B-SIM workflow depth depends on how well the modeling inputs map to the available geometry and material characterization used by the team. Teams that only have partial die or screw definitions may see less actionable output until the missing modeling elements are specified. A strong usage situation is early-stage die screening for profile extrusion where many candidate shapes must be compared quickly.
- +Iterative die studies with controlled geometry-driven reruns
- +Pressure and flow predictions tied to melt-path assumptions
- +Workflow supports engineering comparisons across hardware variants
- +Practical focus on extrusion hardware input preparation
- –Model usefulness drops when screw or die inputs are incomplete

It includes material handling constructs that map formulation or rheology inputs to simulation parameters used in melt temperature and flow response calculations. Governance for repeat runs is driven through saved configurations and parameter sets that support rerunning the same study with controlled input changes.
A tradeoff appears in how much upfront work is needed to define consistent process inputs across thermal and flow steps, especially when shop data arrives with different sampling rates. It fits best when teams already have extruder control setpoints and feeder targets available and want simulation-driven changes that reduce guesswork before hardware or recipe adjustments.

How to Choose the Right extrusion software
Extrusion software in this guide focuses on simulation workflows that connect die and screw configuration to repeatable extrusion outcomes, not just CAD drawing. Ludovic is positioned for geometry-to-run linkage that feeds die features into extrusion simulations without re-parameterizing every change manually. B-SIM and COMPUPLAST VEL round out the rerunnable scenario approach for die and screw iteration from CAD-ready inputs.
Ansys Polyflow is included for physics-based melt transport and thermal modeling tied to die and screw inputs in a single study workflow. Inspire Extrude Polymer adds an extrusion-first workflow that keeps die and screw studies consistent across repeated scenario runs, while AutoCAD is included strictly for DWG-centric extrusion profile geometry automation and extensible geometry and annotation pipelines.
Extrusion software for die and screw simulation, CAD-driven iteration, and repeatable scenario runs
Extrusion software models how die and screw changes alter pressure drop and flow trends across a defined set of operating boundaries, often requiring calibrated melt properties and explicit boundary assumptions. Ludovic emphasizes geometry-linked simulation inputs that turn die feature changes into rerunnable study updates without manual re-parameterization across every iteration.
For teams that build repeatable engineering comparisons, B-SIM and COMPUPLAST VEL support die and screw configuration scenario iteration tied to melt-path and configuration set workflows. When the goal is engineering-grade predictions inside the extrusion path, Ansys Polyflow couples melt transport and thermal behavior in a workflow that handles screw and die inputs together. AutoCAD enters this guide as a geometry automation tool for DWG-native extrusion profile work, not as a deep material response and process simulation engine.
Extrusion simulation capabilities that determine repeatability and engineering traceability
Engineering outcomes also depend on how the tools handle melt properties and boundary assumptions, because pressure drop and flow trends move when melt models and operating constraints shift. Ansys Polyflow focuses on coupled melt transport and thermal modeling so teams can make process-window decisions inside a single physics workflow.
Geometry-to-study linkage with rerunnable scenario workflows
Ludovic moves die features into extrusion simulations without manual re-parameterizing each die change. B-SIM and Inspire Extrude Polymer both maintain die and screw scenario runs intended for controlled repeat comparisons.
Die and screw configuration iteration tied to melt-path assumptions
B-SIM is built around rerunnable melt-path engineering comparisons that connect die and screw inputs to pressure and flow predictions. COMPUPLAST VEL adds configuration sets that lock die geometry plus process inputs to support repeatable process-window tuning.
Physics-coupled melt transport and thermal modeling inside the extrusion path
Ansys Polyflow couples melt transport and thermal behavior in the extrusion path while handling screw and die inputs within one study workflow. This is the most direct option in the set for engineering-grade predictions tied to physics-based behavior.
CAD geometry import for die setup acceleration and geometry consistency
COMPUPLAST VEL uses CAD geometry import to accelerate die setup for repeatable studies. AutoCAD enters as DWG-centric automation that keeps extrusion profile geometry and parametric edits consistent for drawing-driven workflows.
Guided process workflow for repeated design iteration
Ludovic provides a structured process workflow that enables repeated runs during die and screw iteration. Inspire Extrude Polymer similarly keeps an extrusion-first modeling workflow consistent across repeated scenario runs.
Choose extrusion software by iteration model, physics depth, and geometry handling workflow
Next, the decision should separate physics depth from geometry and CAD automation, because Ansys Polyflow prioritizes coupled melt transport and thermal modeling, while AutoCAD targets DWG-native geometry automation without extrusion process simulation depth. Inspire Extrude Polymer lands between these roles by centering extrusion-first die and screw studies that stay consistent across repeated parameter changes.
Select the rerun-first workflow if the team iterates die geometry frequently
Choose Ludovic when geometry-linked die features must feed extrusion simulation updates without manual re-parameterizing every change. Choose B-SIM when repeatable die iterations require rerunnable melt-path comparisons built around controlled scenario runs.
Lock die geometry plus process inputs if repeatable process-window tuning is the goal
Choose COMPUPLAST VEL when configuration sets must bind die geometry with process inputs to support controlled reruns. This option fits teams that tune parameters against a defined process window instead of rebuilding each study from scratch.
Pick Ansys Polyflow when coupled melt transport and thermal effects drive the decision
Choose Ansys Polyflow when die and screw simulations must include physics-based melt transport and thermal coupling in one study workflow. This is the right choice when pressure drop and thermal behavior both need engineering-grade predictions tied to operating boundaries.
Choose CAD automation tools only when the requirement is extrusion geometry output consistency
Choose AutoCAD when the priority is DWG-native extrusion profile geometry, standardized drawing outputs, and extensible scripting for geometry and annotation pipelines. This avoids over-allocating engineering time to simulation tasks that AutoCAD does not target.
Use Inspire Extrude Polymer when repeated die and screw studies must stay consistent across parameter edits
Choose Inspire Extrude Polymer when the workflow must remain extrusion-first and keep die and screw studies consistent across repeated scenario runs. This choice fits teams that want parameter comparison across repeatable studies without expanding into multi-tech process chain coverage.
Who benefits from geometry-linked rerunnable extrusion simulations
Physics-focused engineering teams also benefit when the simulation captures coupled melt transport and thermal effects in a single workflow. Ansys Polyflow targets this requirement using extrusion-path modeling that ties predictions to screw and die inputs and explicit boundary assumptions.
Extrusion process engineers running repeatable die iterations from CAD-ready inputs
B-SIM is designed for rerunnable melt-path engineering comparisons and controlled scenario iteration. Ludovic adds geometry-to-run linkage so die feature edits feed simulation updates without re-parameterizing each change manually.
Design engineers that need process-window tuning tied to locked configuration sets
COMPUPLAST VEL supports die geometry plus process inputs locked into configuration sets for controlled reruns. This approach keeps tuning aligned to the same scenario workflow during iteration.
Simulation engineers prioritizing physics-based coupled melt transport and thermal predictions
Ansys Polyflow provides a coupled melt transport and thermal modeling workflow inside the extrusion path. It handles screw and die inputs in one study so teams can connect pressure drop and flow trends to thermal behavior under defined operating boundaries.
Mechanical design teams focused on DWG-standard extrusion profile geometry automation
AutoCAD supports DWG-native automation for extrusion profile geometry, parametric edits, and repeatable drawing and solid generation. This fits teams that need geometry consistency without deep material response and extrusion process simulation modeling.
Common buying mistakes in extrusion simulation tool selection
Another frequent failure mode comes from treating model setup as interchangeable across materials, because each tool ties predictions to melt property calibration and boundary definitions. Simulation accuracy and first successful runs depend on calibrated material characterization and careful boundary assumptions.
Choosing a geometry-first CAD tool for extrusion process simulation work
AutoCAD is built for DWG-centric extrusion profile geometry automation and annotation pipelines, so it has limited extrusion process simulation and material response modeling depth. Simulation teams that need pressure drop and flow trend predictions should prioritize Ludovic, B-SIM, COMPUPLAST VEL, or Ansys Polyflow.
Assuming rerunnable workflows work without calibrated material and boundary definition
Ludovic simulation accuracy depends heavily on calibrated material and boundary assumptions. Ansys Polyflow setup requires careful definition of melt properties and operating boundaries, so lack of characterization slows first usable results.
Buying die and screw scenario tooling while providing incomplete inputs
B-SIM model usefulness drops when screw or die inputs are incomplete, because melt-path predictions depend on scenario completeness. COMPUPLAST VEL also slows when input data harmonization is time-consuming for mixed source signals.
Underestimating setup and model-prep effort for complex geometry
Ansys Polyflow CAD import friction can slow die and channel geometry preparation, which impacts throughput. Ludovic and B-SIM both require careful model setup and verification for complex cases, so teams should plan validation time.
