Question about using TSTEPNL

Creator
Creator

Hello everybody. I am new here.

 

My question is how do I get NX Nastran to use the TSTEPNL modeling object/card in case control?

 

I am trying to perform a SOL601,129 solution and in the Solution Attributes --> Case Control --> Time Step Intervals - it doesn't let me select the nonlinear transient parameter (TSTEPNL) for that, so how do I make that happen?

 

Is the TSTEPNL card "required" for SOL601,129 or will the TSTEP card suffice?

 

Any help in this would be greatly appreciated.

 

Thank you.

TSTEPNL is not supported in Advanced Nonlinear (SOLs 601,x or 701). See Remark 15 here:

https://docs.plm.automation.siemens.com/tdoc/nxnastran/11/help#uid:index_QRG:id512196:id510921:id511...

 

And the description here ("TSTEPNL is intended for SOLs 129 and 159"):

 

https://docs.plm.automation.siemens.com/tdoc/nxnastran/11/help#uid:index_QRG:id511876:id509346

 

Note that SOL 129 <> SOL 601,129

Ahhh...okay.

 

That explains it then.

 

Thank you.
