Eigenvalue Buckling Error

    • Arvind Sinha

      I performed a structural analysis with some loading and then coupled that solution to eigenvalue bucking. Choose 2 modes. I get the following error. Any help will be appreciated.

      *** ERROR ***                           CP =     285.625   TIME= 08:38:02

      It is not possible to know for sure, but this could be memory related (not enough Ram) - try reducing your model and run a smaller subpart.

      If it is not a big model, try run with non-distributed mode on (so smp).

      Hi Arvind

      SEGV is a data error - could be data from memory, storage, network, etc.  Which also means that nearly anything could be the cause i.e. bad input, bad hardware, program error etc.  516 GB of RAM is a lot, but still finite so there will be a limit to model size that you can solve...but I don't think that is the problem (for now).  Are there any other warning or error messages in the output file you can share?  If you are an Ansys customer can you please open an service request for this.
