[Solved] COQUE_3D Post Processing

Hi,

I'm trying to post process a COQUE_3D analysis and have one again run into the problem that neither Paravis nor PostPro can do this directly:

1) Is there a work flow that works for Paravis? Or for that matter PostPro?

2) I've tried PROJ_CHAMP as below to create linear element results, but this doesn't work for triangles. The tri's don't take on a resultant value( deformation or stress). Does anyone know how I can fix this?



lin_mesh=CREA_MAILLAGE(MAILLAGE=m_quad,
                       QUAD_LINE=_F(GROUP_MA='m_all',),);

lin_pall=AFFE_MODELE(MAILLAGE=lin_mesh,
                     AFFE=_F(GROUP_MA='m_all',
                             PHENOMENE='MECANIQUE',
                             MODELISATION='3D',),);

PROJ=PROJ_CHAMP(RESULTAT=STATIC,
                MODELE_1=pallet,
                MODELE_2=lin_pall,);

IMPR_RESU(MODELE=lin_pall,
          FORMAT='MED',
          RESU=_F(MAILLAGE=lin_mesh,
                  RESULTAT=PROJ,
                  NOM_CHAM=('SICO_ELNO','SIEQ_ELNO','EPSI_ELNO','SIEQ_NOEU','EPSI_NOEU','DEPL','SIEQ_ELGA',),),);


Thanks for the help.

Gary

Paravis should work, what is the problem ?

Using PROJ_CHAMP is of course a good idea but why don't you project on a quadratic mesh (QUAD8 or TRIA6) ? This should be OK.

Hi Thomas,

Many thanks for your reply. If I don't use PROJ_CHAMP Paravis displays the element central nodes with a zero result. I've now projected the results to my original quadratic mesh (no central nodes) instead of to a linear mesh and it works perfectly. I really like Paravis.

Thanks again.

Gary

hoi Gary

can you give the code (comm file) of how you implemented this projection here?

kind regards - kees

Hoi Gary

I glanced through the code and for now it is just what I am looking for.
Thank you for the upload. I will check the relevant part for me later on (it is holliday season for me as well).

Kind regards - kees
