Check Contact Force
This check box is available only for analyses of models that contain contacts. Select Nonlinear / Use Load Histories on the analysis definition dialog box. Contacts is highlighted. The Check Contact Force check box is now active.
For a static analysis with contact, Creo Simulate uses stiff distributed springs to prevent interpenetration of the two opposite surfaces, in the case of 3D models, or curves in the case of 2D models. By default, a displacement based check is used to make sure interpenetration is low enough. If not, Creo Simulate increases the spring stiffness.
If you want to ensure that you obtain an accurate result for the contact force, select Check Contact Force on the Convergence tab of the analysis definition dialog box. Creo Simulate will then stiffen the springs until the value of the contact force converges.
