Applying Frictionless Constraint in Autodesk Simulation Mechanical


The frictionless constraint is used to resist the deformation of the selected surface in its normal direction due to the force applied on the model. You can select planar and cylindrical surfaces of a model to apply frictionless constraint by using the Frictionless tool of the Autodesk Simulation Mechanical.

To apply frictionless constraint to a surface of the model, select a surface and then choose the Frictionless tool from the expanded Constraints panel of the Setup tab in the Ribbon of the Autodesk Simulation Mechanical; the Creating Frictionless Constraint Object dialog box will be displayed, refer to figure given below. In the Description exit box of this dialog box, you can enter a comment or description about the frictionless constraint being applied. Next, choose the OK button; the frictionless constraint will be applied to the selected surface.

Creating Frictionless Constraint Object

Below Figure A shows the model with frictionless constraint is applied at the bottom planar surface of a structure member in FEA editor environment of Autodesk Simulation Mechanical and Figure B shows the same model in the Result environment of Autodesk Simulation Mechanical after performing the analysis. Note that as the frictionless constraint is applied, the selected surface will not be allowed to deform in its normal direction, refer to Figure B.

  1. I have a part in autodesk inventor that I am importing to Simulation Mechanical 360 (cloud based). It works fine on the non-cloud program, but will not run with Frictionless constraints in 360. If I take these out, it runs fine, but it is not a realistic scenario at that point. Any thoughts?

    Thanks
