![]() External load is parallel to contact element as shown below.Little or no sliding between contacting surfaces.Very small or no gaps between contacting parts.Non-Linear Contact Interactions:īasic no penetration contacts in a static study default to a “Linear” contact algorithm where certain assumptions are made to improve solution speed. When using contact interactions in SolidWorks simulation, one should know the difference between linear and non-linear contact interaction and the implication of various contact interaction settings. The assumptions and theory behind contact interactions need to be understood in order to avoid these modeling errors and generate accurate, robust, and reliable results. Even for advanced FEA users the definition and analysis of contact interactions is not quite straightforward and is vulnerable to modeling errors as contact interactions can introduce non-linearities in the FEA model.
