Every object in your simulation environment must be assigned a specific behavior type and material profile. Object Classification
Select the Workpiece object, click > Import , and select your 3D CAD file (typically in .STL , .STEP , or .IGS format). Repeat the import process for the Top_Die . Step 4: Material Assignment and Mesh Generation
The CVN ME Academy provides high-quality walkthroughs on initial setup and forging simulations.
Utilize local mesh refinement windows. Place a "Mesh Window" around sharp die radiuses to force the software to generate smaller, denser elements only where complex folding occurs. deform 3d tutorial
, a premier finite element method (FEM) software for simulating manufacturing processes like forging and machining, follow these structured steps based on official lab guides and training materials. Scientific Forming Technologies Corporation 1. Core Simulation Workflow
This DEFORM 3D tutorial gave you the skeleton of a simulation: Geometry -> Mesh -> Material -> Movement -> Contact -> Run -> Analyze.
Whether you are a manufacturing engineer looking to optimize a forging die, a student writing a thesis on grain flow, or a machinist wanting to understand why your parts crack, this will take you from zero to a functional simulation. Every object in your simulation environment must be
Here's how to start:
Define the : Choose Constant Velocity for hydraulic presses, Mechanical Crank for mechanical presses, or Screw Press depending on your real-world equipment.
Once the simulation completes, click the icon to extract actionable engineering data. Step 4: Material Assignment and Mesh Generation The
| Problem | Likely Cause | Solution in Deform 3D | | :--- | :--- | :--- | | | Missing movement on Top Die | Check Object 2 "Movement" tab. Ensure "Die Load" is not zero. | | Mesh blows up / Tangles | Step size too large | Reduce "Step size to mesh ratio" below 0.5. Enable "Frequent remeshing" (every 5 steps). | | Volume loss (Object gets smaller) | Punch exceeds boundary box | Increase the "Stroke limit" or move the die starting position closer. Lower the "Penalty" stiffness. | | Too slow (Days to run) | Too many elements | Reduce element count. Use "Local Mesh" (fine only at contact). Increase Step size slightly. | | Folding defect predicted | Bad die geometry | In Post, use "Fold" detection tool. Redesign die radius. |
For complex parts, DEFORM-3D's capability is invaluable. When elements become too distorted during large deformations, the system automatically regenerates the mesh, allowing simulations to continue without interruption.
For aerospace parts, you need to predict recrystallization.
