use ETABLE as a body load
use ETABLE as a body load
(OP)
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
http://www.eng-tips.com/threadminder.cfm?pid=569
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

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%
