Meshing Error: “The surface mesh is intersecting or close to intersecting, …”

      Hello everyone,

      I ended up importing the geometry from Solidworks, and refining it in Spaceclaim (not sure if this helps in any way). I have also checked for any geometry errors and the subsequent steps, when it came to further refinement of the geometry - which still gave me zero errors

      However, when it comes to the default meshing of the car, I am getting the following errors, as shown in the picture. Is there any way to figure out, where this might be happening, as to adjust the geometry if necessary or is there any other step that could be done to avoid this error?

      Still very new to Ansys, so any help is more than appreciated

      Please check geometry in SpaceClaim. 
      Select geometry in structure tree --> Use right click --> Select Check Geometry. (Or Tools - Fault Detection in DM)
      The geometry should be error free to proceed. 
      If geometry has any errors, please modify/recreate geometry at those places. 

      If geometry is ok, you will need to work on sizing. Please check help document for sizing.
