Modal Analysis of a Monocoque Course Troubleshooting

    • AeroMike

      Hello. I'm currently taking the course "Modal Analysis of a Monocoque" and I'm encountering some difficulties. I'm running the simulation on 19.2 release. Please refer to the tutorial videos featured in the course to understand my issues. 

      First of all, I can't manage to transfer data from ACP(Pre) to Static Structural as the mentor does in "Physics Setup - Lesson 5, Setup the twist test". Secondly, in Ansys Mechanical I get a yellow warning stating "Two or more remote boundary conditions are sharing a common face, edge, or vertex. This behavior can cause solver overconstraint and is not recommended, please check results carefully. You may select the offending object and/or geometry via RMB on this warning in the Messages window".

      Can someone help me please? I'm willing to provide more info on request. Thank you.

      If the results look fine then you can ignore the warning. The following may explain the cause of the warning:


      one or more mpc contact regions or remote boundary conditions may have conflicts… (
