    Hi Prakash, 

     

    Any updates?

    I am trying to get K4AAX Structural Damping Matrix using CMS Methods available in Optistruct , Like CMSMETH Cards etc.

    But its having certain limit for DOF to calculate matrix.

    I am getting below error

      *** ERROR # 3450 ***
      The number of specified ASET DOF is beyond solution limit.

     

    What is the Limit Value ? How much Maximum Nodes we can have in ASET ?

    And is there any way to increase solution limits ?

     

    Thank you
