Missing BRIC20 in ASCII _0000.sty output file

[victorkemp]

When I have a BRIC20 and TETRA10 in the same model, the ASCII output file for the mesh shows only the TETRA10, like this:

/SOLIDE
3d Solid Elements
#FORMAT: (4I10/8X,8I10) 
# SYSSOL  USRSOL  SYSMID  SYSPID
#SYSNOD1 SYSNOD2 SYSNOD3 SYSNOD4 SYSNOD5 SYSNOD6 SYSNOD7 SYSNOD8
         1         1         1         1
                 4         4        27        27         1        28        28         1

If I remove the TETRA10, then the BRIC20 appears under /SOLIDE as you'd expect.

How can I get it to include the BRIC20? That mapping from SYSSOL to USRSOL is necessary to interpret element data from the other .sty files.

Dear Victor, thanks for your interest in OPenRadioss and for your patience, please, try to use STA file format instead of STY which are obsolete. Please, have a look to the Radioss documentation as starting point:
https://help.altair.com/hwsolvers/rad/topics/solvers/rad/radioss_starter_engine_setup_ascii_output_r.htm
Hope this help to fix this issue.

Kind Regards,

Eric

Thanks Eric. Would you recommend STA as a useful output format for a general purpose 3rd party post-processor? Or maybe Annn is better since that's what the VTK converter uses?

[elequiniou]

Hi Victor,
The purpose of this STA-file is to save the state of element and then make it possible to include it into a _0000.rad file for Radioss Starter for initialization of a second run, for instance some stamping simulation results to serve as initial conditions of a crash simulation.
For general purpose output, I'd recommend H3D if the postprocessing tool is Altair HyperWorks.
For third party post-processing, go with animation (Annn) as it is possible to use several converters, VTK (Paraview) and now D3plot thanks to this recent community contribution, please see: https://github.com/orgs/OpenRadioss/discussions/2790
Another possibility I see would be to put in place some HDF5 output format, but the code infrastructure is not there yet.

Hi,
Another question on .sta file. We are testing TAB2 failure model to benchmark with GISSMO and found that they matched well with each other. But we found /INIBRI/FAIL/TAB2 is not listed in the help file:
https://help.altair.com/hwsolvers/rad/topics/solvers/rad/inibri_fail_starter_r.htm

Is TAB2 related damage info. supported to be output?

Thanks.

[vdavaze]

Hi @disruptorwin

Thanks for your question.

/FAIL/TAB2 should be listed in the help file indeed. It is compatible with /INIBRI.

We'll correct the documentation soon.

Thanks a lot.

Valentin.

Thank you very much!
