Ansys Explicit Dynamics Tutorial ((new)) ★ Fully Tested
: Apply Mass Scaling in the Analysis Settings. This artificially adds mass to the few tiniest elements to scale up their allowable time step without significantly impacting the global inertia of the structure.
In the world of engineering simulation, understanding how products behave under extreme conditions is not just a luxury—it is a necessity. While standard structural simulations handle static loads and slow deformations with ease, they often falter when physics gets violent. When an automobile crashes, a cell phone drops, a bullet penetrates armor, or a metal sheet is stamped, the physics change entirely. This is the domain of . ansys explicit dynamics tutorial
Add materials like , Aluminum text-plastic , or Johnson-Cook models (ideal for high-velocity impacts). Step 3: Geometry Preparation and Cleanup Right-click Geometry and open SpaceClaim or DesignModeler. : Apply Mass Scaling in the Analysis Settings
Symptoms: Solver warns "Time step < 1e-10." Cause: One tiny, low-quality element. Fix: Mesh > Show > Bad Elements . Use Mesh Metrics > Aspect Ratio – fix elements > 20. Add materials like , Aluminum text-plastic , or
Wait – why not model the free fall? Because solving 0.45 seconds of falling with tiny time steps would take days. We use the Initial Velocity condition to start the analysis 1ms before impact.
. This guide summarizes the standard workflow for setting up a simulation in Ansys Workbench as of April 2026. 1. Material Selection (Explicit Library) Unlike static simulations, you must use materials from the Explicit Materials library
By the end of this guide, you will be able to simulate a metal block being crushed by a rigid impactor—a classic validation problem.
