TSTEP is automatiocally adding in nonlinear quastatic analysis

mpvnaresh

Hi 

I am rinning a nonlinear quastatic analysis . I am putting it for solve its giving an error  

 *** ERROR # 1461 *** in the input data:
 Card 'TSTEP(TIME)' is not allowed for this subcase type.

 

 the input data TSTEP is adding on its own .how to deactivate this .?

Hi, 

 

there is no TSTEP entry for nonlinear quasistatic analysis. Make sure you are choosing the correct analysis type- it should be non-linear quasi-static not generic.

The NLPARM and TSTEP load collectors share the same ID (3). Each LC needs a unique ID, which might be causing the error.

But i am not adding the time step . I dont know why it is adding in all the solutions.

When iclick on optistruct to solve ,In the deckfile TSTEP is being created.

After i deleted the .tcl and hm.setting files from My Documents the problem got resolved .

Thanks for the support.

Hi ! 

TSTEP is for transient analysis. 

If you want to run Non Linear Quasi Static Analysis, NLPARM is sufficient /emoticons/default_smile.png' srcset='/emoticons/smile@2x.png 2x' title=':)' width='20' />

Hi All

 

I did not create any TSTEP .I created a Non linear Quasistatic solution ,and exported(solver deck file).

In the FEM file i observed a TSTEP card  is added.For all the solution (Liner or Nonlinear )TSTEP is automatically added in the deck file.

After i delete the .tcl and .settings file from the documents , The problem got resolved.

Please make sure to set the analysis type as nonlinear static instead of generic in loadstep.
