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
