Incremental output of GPFORCE or SPCFORCE in NLSTAT simulation

Altair Forum User

Hi,

I'm running a NLSTAT (quasi static simulation) analysis with geometric and material nonlinearities with large displacements. I need Reaction forces of all incremenets in a specific spc node to get the FORCE/TIME STEP graph. I read before that this output of GPFORCE or SPCFORCE is not supported in older versions. What about the latest one? Is there something I have missed? Also what is your suggestion on alternative, if that output is not supported? Dynamic implicit simulation?

 

Thanks for your answer!

Hi @mihabreznik

 

This feature should be available with NLOUT option and HyperWorks update 14.210.

 

Please give it a try /emoticons/default_smile.png' srcset='/emoticons/smile@2x.png 2x' title=':)' width='20'>

Hi,

 

I'm getting the same problem using Hypermesh 2017.2

Any suggestions?

 

Thanks,

Hi,

 

Increment are automatically adjusted by default (PARAM>EXPERTNL>AUTO). The increment can be fixed using either:

• PARAM>EXPERTNL>NO
• NLADAPT>DIRECT>YES
• DTmax=DTmin (NLADAPT)

Unfortunaterly it still doesn't work

 

I have to punch a file with the spcforce at every iteration.

It works for stresses, but not with spcf. COuld you help me please?

Thanks

The shared model works on my end as SPCF and GPFORCE are output at every increment:

 

<?xml version="1.0" encoding="UTF-8"?>

could you share the .fem file?
