simpleBoundaryConditions.scn

An FEM cube is stretched using a pressure field applied on one face, while the opposite face is maintained on a plane.
This scene contains typical boundary conditions involved in mechanical validations:

• Surface pressure
  
• Constraining particles to a plane, or to a line, or to a point
  

The constraints allow the constrained particles to freely slide on the plane without global translation or rotation.
The pressure applies uniform forces.
As a result, the object keeps a box shape with plane, orthogonal faces.
