Frequently Asked Questions

Pressure

Pressure in a structural analysis context, is a force applied uniformly over a surface. It's distinct from a point force because its effect is distributed, and it's measured as force per unit area. In structural analysis, correctly applying pressure loads is crucial for accurately predicting how a component will deform or fail. SimSolid provides various pressure loading options to simulate real-world conditions.
