Usually, it means that some mesh controls - like the controls that set the surfaces for inflation - may not be applying to the same surfaces as before. The failed topology should blink three times. Currently, only the Patch Conforming Tetra mesh method uses the target limits to improve the mesh. As Speos can be embedded into various CAD environments, it relies on meshing algorithms coming from CAD. Automatic contact match detection can result in undesirable contact matches. It means, from same meshing values, meshing representation can be different from one CAD platform to another. Sweeping failed because one or more side faces can Contact match errors may occur due to tolerance issues or mesh size differences. Generally, fixing the bad quality surface mesh is the best way to fix the volume mesh because bad quality mesh is usually a result of the geometry over-constraining the mesh topology.
