use ETABLE as a body load

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

RE: use ETABLE as a body load

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%
