Deform 3d Tutorial -
DEFORM-3D is used to analyze flow, stress, strain, temperature, and microstructure evolution during forming. Common applications include: Forging (Open and Closed Die)
Before opening the software, ensure your CAD models (Die and Workpiece) are saved in a compatible neutral format. is highly recommended for DEFORM 3D because the software relies heavily on surface mesh definitions. Creating the Project Open the DEFORM 3D Main Window.

| Issue | Likely Cause | Solution | | :--- | :--- | :--- | | | Interference (dies penetrating billet at Step 0) | Move the dies apart in CAD, or use Inter-object -> Positioning to separate them. | | Mesh tears apart / Negative Jacobians | Step size too large. | Halve your Step size per stroke (e.g., from 0.075mm to 0.0375mm). | | Load is 1,000,000 tons (unrealistic) | Material is defined in tons/mm² but your units are wrong. | Check Simulation Controls -> Units before running. | | Billet flies away | Forgot to set friction. Frictionless metal slides infinitely. | Set Friction: Shear 0.12 . | deform 3d tutorial
Compare simulation results with a physical, simple test case (e.g., cylinder compression) to validate your material model.
Identifying "laps" (folds) or areas where the material might crack.
Tip: Monitor the log file during execution. If the simulation experiences a "Negative Jacobian" error, it means elements have become severely distorted. Ensure that is enabled in your simulation controls so DEFORM can automatically pause, rebuild a clean mesh, and continue calculations. 8. Step 7: Post-Processing and Defect Analysis
Assign a velocity to the Top Die (e.g., -10 mm/sec in the Z-direction). DEFORM-3D is used to analyze flow, stress, strain,
If your CAD alignment wasn't perfect, use the Movement tool in DEFORM to translate or rotate the dies until they barely touch the workpiece surface.
Usually, dies are defined as Rigid to save computation time, assuming they won't deform under load. Phase C: Meshing the Workpiece
mode in the Pre-Processor to ensure no critical data is missed. 2. Defining the Objects
Before we dive into the steps, you must understand the structure of DEFORM. Creating the Project Open the DEFORM 3D Main Window
When you launch Deform 3D, you will see the main interface divided into several sections:

This comprehensive tutorial provides a step-by-step guide to setting up, running, and analyzing a 3D metal forming simulation in DEFORM-3D. Understanding the DEFORM-3D Workflow
Run a sensitivity study to ensure the mesh is fine enough that further refinement doesn't change the results.
