Subject: Size of the RST file versus RTH file
Author: Vincent Raillard
Date: 1999-01-19 04:05:00I have some news about my problem:
I found a trick to limit the size of the result file. Now, I issue the
following commands:
OUTRES,ERASE
OUTRES,ALL,NONE
OUTRES,NSOL,LAST
Previoulsy, I only issued OUTRES,ERASE and OUTRES,NSOL,LAS and it didn't work
as it should.
It is the unique way to force ANSYS to only write nodal solution data of the
last substep.
The size of my .rst decreased from 250 Mb to 5 Mb.

Objet : RE: XANS: Size of the RST file versus RTH file
The difference probably is the element results. For the thermal
model you have much less data for
the elements.
Try restricting both files (via the result file options) to just the
solution vector, the difference should be
more like the factor of 6. Also by default we put all the stresses,
strains, temperatures, etc on the result
file. Again, OUTRES will allow you to reduce this to only the items
needed.
Also, try a SET,LIST in post1 to make sure only the single data set
which you expect is there.
