Follow this standard procedure to set up a robust drop test or impact simulation using the component. Step 1: Core System Setup Open ANSYS Workbench .
must remain perfectly constant (a flat horizontal line) throughout the run.
: Set a high limit (e.g., 10,000,000 ) to prevent the solver from stopping prematurely. ansys explicit dynamics tutorial
| Parameter | Recommendation | | :--- | :--- | | | Hexahedral (brick), linear order | | Time Step Scale Factor | 0.9 (stability margin) | | Contact Pinball | 10% of element size | | Mass Scaling | Use sparingly (only for quasi-static explicit). Max allowed DT = 1e-6. | | Output Requests | Save only at 100-200 frames. Do not save all time steps. | | CPU Cores | Explicit solves scale linearly. Use HPC license for >4 cores. |
Any part with Stiffness Behavior = Rigid will not deform. Use this for tools, floors, or impactors to speed up solution by 10x. Follow this standard procedure to set up a
Simulate a steel sphere impacting an aluminum plate at 200 m/s to observe deformation and potential penetration.

must stay under 5% to 10% of the total energy. High hourglass energy means your mesh is unstable and yielding false displacements.
