DEFORM 3D is a powerful Finite Element Method (FEM) simulation tool used widely in industry and research to analyze 3D material flow in manufacturing processes. This comprehensive tutorial walks you through the essential stages of setting up, running, and analyzing a metal forming simulation. 1. Introduction to the DEFORM 3D Workflow
Set initial temperatures for the die (200°C) and the workpiece (1100°C for hot forging), as well as heat transfer coefficients. Step C: Running the Simulation Database Generation: Create the simulation database.
Once the simulation completes, click the icon to extract actionable engineering data.

This is where you define the physical components of your simulation.
Now you must tell the solver how the top die moves and when the simulation should stop. Die Movement Select the . Go to the Movement tab.
Where you define your system. You import CAD files, generate the finite element mesh, assign material properties, and set up movement and thermal conditions. DEFORM 3D is a powerful Finite Element Method
The visualization tool where you analyze the results, check for defects like underfilling or folds, and extract force-stroke curves. 2. Phase 1: Pre-Processing Setup
After a forming simulation, you can transfer the contact loads to a die stress model. This helps evaluate whether the die can withstand the forming forces without failure. The Die Stress Analysis wizard automates this transfer, accounting for constraints and interference fits.
Set the relationship type to (where the rigid die is the master and the plastic workpiece is the slave).
Set the and choose the Process Type (e.g., Forming). Select the Primary Operation (e.g., Forging). Define the Units system (SI or English) and click OK . Step 3: Importing and Preparing Geometry Introduction to the DEFORM 3D Workflow Set initial

Add two more objects, changing their types to (these will be your Top and Bottom Dies). Import their respective geometries. 3. Step 2: Mesh Generation for the Workpiece
Contact between the workpiece and dies governs material flow. Proper friction modeling is essential for predicting realistic deformation.
