SOLIDWORKS Simulation: ‘Mesh creation failed’ Why Won’t my Part Mesh?

General News

Summary

A good mesh is key to any successful Finite Element Analysis and extracting accurate, valid results. If there are any noticeable small or thin features, then it would be best to apply a finer mesh on these faces as well. Similarly, turning on the option for ‘Remesh failed parts with incompatible mesh’ gives the SOLIDWORKS Simulation mesher additional freedom to mesh the interfaces of components independently so the sizes of the elements can be dissimilar. As shown below, any holes or missing faces in the shell body indicate problem areas for SOLIDWORKS Simulation. Therefore, if the shell mesh is successful at capturing all the faces of the geometry then there is most likely a thin feature that the 3D tetrahedral elements are unable to fill.
