use ETABLE as a body load

[marceljaner]

Hi,
I am trying to make a very simple (visco)elastic-thermal coupled analysis for which I obtain the strain of each element and I want to generate a body load (HGEN) that depens on this strain.

I obtain the strain usin ETABLE

ETABLE,STRAINTABLE,EPTO,EQV

I modify the table

SMULT,TABLEMOD,STRAINTABLE,,NUMBER

and I want to introduce the new table as a body load

BFE,ALL,HGEN,TABLEMOD

The problem is that this method doesn't work. In fact, BFE only allows to introduce variable forces defined with *DIM.

Does anybody know if there is any way to pass from ETABLE to *DIM?

There is any better way to introduce this body forces from strain results?

Thank you

You can use your method above but you will need to transfer your ETABLE data to a "table" which has been dimensioned using the *DIM declaration. This is explained in the help manual under BFE.

Thank you!

I've followed your suggestion and I think I've solved it. If anybody needs to convert an ETABLE to a TABLE, I put the code here


*DIM,VECTOR_TABLEMOD,TABLE,NUMBER_ROWS_TABLEMOD,1,1

*VGET,VECTOR_TABLEMOD(1),ELEM,1,ETAB,TABLEMOD

BFE,ALL,HGEN,1,%VECTOR_TABLEMOD%
