      Hi,

      Greetings of the Day!!

      I am trying to exprot stiffness matrix from modal anlysis, I have followed the following video still I am not able to export stiffness matrix.

      This the command I used:

      *DMAT,MatKD,D,IMPORT,FULL,file.full,STIFF
      *PRINT,MatKD,Kdense.matrix

      In the command file under solution tree. It shows the following.

      File status shows: File not found.

      video link :

      .

      The file.full this file is missing in the analysis folder.

      How to rectify this?. Kindly guide to sort this out.

      Hello Kavi,

      Go to Analysis Setting>> Analysis Data Management. Set the option 'Delete Unneeded Files' to 'No'. After this you need to clear generated data nad re-solve the Modal analysis.

      Hi Kavi,

      Try solving using SMP mode. For SMP mode, you need to uncheck the 'Distributed' option.
