Hi everyone,

I applied the solidDisplacementFoam to analyse a simple case, a plate (1m*1m*3mm) with four edges fixed ,and put a constant 10 Pa force on one of the remainder face, the other with 0 Pa(using tractionDisplacement BC). The geometry is in like picture "Selection_016.png". and I set the d2dt2Schemes under the fvSchemes dictionary Euler. The displacement of the point at center of the plate is like the "Selection_017.png". It seems that there is nonlinear factors in it.

But the solidDisplacementFoam solver is a linear solver, I was really confused about this. Anybody can help me with this... I would appreciate it very much.

Wishes,

Xiaoxue
