Hi, I am trying to model deformation of foam in Optistruct (Non linear quasi static, NLSTAT subcase) by imposing displacement of top plate through the foam and constraining the bottom plate. Though my model is converging, you can see the foam penetrates the bottom plate (green). Three contacts have been defined in the…
