<p>For some background, the Chassis 3d file is made in SolidWorks and I would export it to a .step file in ANSYS Workbench. From there, I would follow the official ANSYS Chassis Analysis tutorials and I would run into problems in meshing. These are the type of errors I would get:<\/p><\/p>\n

  1. <strong id=”docs-internal-guid-08ce76b2-7fff-9158-98a2-13627fe7075d”>A solver pivot warning or error has been detected in the UY degree of freedom of node 111607 located in Surface Body. This is usually a result of an ill conditioned matrix possibly due to unreasonable material properties, an under constrained model, or contact related issues.  Check results carefully. You may select the offending object and\/or geometry via RMB on this warning in the Messages window.<\/strong>\n

    1. This was the most prominent error I received every time I tweaked the geometry of the chassis in SpaceClaim with making it a line body and applying a cross section on it.<\/li>\n<\/ol>\n<\/li>\n
    2. <strong id=”docs-internal-guid-9fa6c0b2-7fff-ba64-dedc-1e4c61a28659″>The program has detected a tubular cross section that contains a bend. Consider using a “pipe idealization” condition in order to capture possible cross section distortion.<\/strong><\/strong>\n
        \n
      1. I’ve actually tried making every bended pipe an idealized pipe but that caused even more errors. From what I understand, this is moreso for CFD…? I could be wrong.<\/li>\n<\/ol>\n<\/li>\n
      2. <strong id=”docs-internal-guid-c75a3c50-7fff-cea2-bf1c-d20439174997″>The element option BEAM188 was either not ordered with this ANSYS installation or the appropriate product was not selected for this session.<\/strong><\/strong><\/strong>\n
          \n
        1. I saw this error only once and I just had to restart Workbench.<\/li>\n<\/ol>\n<\/li>\n<\/ol>\n

          <p>I’ve only had a single mesh study run successfully and whenever I try to replicate the steps from the ANSYS YouTube tutorials, it still always gives me error #1 and #2. I’ve also tried meshing our chassis using Discovery and running almost all of the repair functions in the Repair Ribbon tab. It meshed incompletely.<\/p><p> <\/p><p>I would like some input on what I’m doing wrong.
