  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.

  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.
