Warning message

Hi,

ANALYSIS RESULTS :
------------------

 
 *** INFORMATION # 1420
 Unsupported solution sequence, switching run to serial mode.
 
 *** WARNING # 1418
 Parallel OptiStruct (-ldm) cannot handle some subcases defined.
 Switch to serial run or parallel run with domain decomposition method (-ddm).

 

I am getting the above warning message, i need to know the reason for this message, is this because of the SMP run? 

 

Regards,

It is because of sub model analysis. I believe domain  decomposition  method(ddm) does not support that.

Hi,

 

If it doesn't support ddm then it automatically switches to the the other method ?? Since my run has completed do i need to suspect the result?

Yes it is switching from parallel computing to serial computing.In upcoming version of OptiStruct , we might support for ddm for submodel analysis.I think results should be fine.Please also refer OptiStruct online help for detailed information on subcase specific modeling.

Hi,

  

So optistruct models doesn't support ddm method?? i tried with different models and i am getting the same warning message, 

I am trying to run my optistruct job on a linux machine with multiple cores.

But irrespective of the number I give, my job runs only on one CPU.
