plot

[M. Kurdi]

Hello,
Is it possible to specify an absolute scale in plotting deformed and undeformed solutions?

Let me explain. I am using the plot command to display the deformed and undeformed solutions. I would like to maintain the same scale between two different evaluations of the finite element model, so that I can compare the two solutions. For example I use one run

PLOT SCALE,1,0
PLOT UNDEF,1,1
PLOT MESH
PLOT DEFO,1,1
PLOT,POSTscript !close file
But when running same model but different forces the deformations is different and the scaling adjust to that particular solution. But that will not allow comparison of the two runs.
Thanks,

Mohammad

use the plot command RANGe; i.e.

plot,range,v1,v2

Thanks.
I think the problem is with the PLOT SCALE command. Each run is scaled differently to accommodate the different deformed structure, so I get different scaling. When I use Range while disabling scale part of the solution is clipped off.
In using the PLOT RANGE, what are the maximum and minimum allowed values for the plot size that one can use?

I found a work around by using PLOT CENT AND PLOT RANGE. Just made sure all solutions can fit in the range provided by centering the plot every time.
