Modal – SPMWRITE Significant Figures – State Space Matrices

    • Callan Morey

      Hello, I'm trying to increase the number of significant figures when using the SPMWRITE command in Modal analysis. I can't seem to increase it at all. Any help would be appreciated. Thanks.

      Hi Callan,


      Try this:

      /GROPT,DIG1,n (n = # of significant digits before decimal)
      /GROPT,DIG2,n (n = # of significant digits after decimal)

      Hi Ashish,

      I tried your reccomendation above and no change to my matrix.

      I placed the /GROPT in the solution command at the top, before any of the SPMWRITE command.

      Have you got another idea?
