View mode shape

[eroz]

Trying to display the mode shape of a model. Used:

set nEigen 1
display -$nEigen 0 $dAmp; # display mode shape for mode $nEigen

However, I am getting:

invalid command name "display"
while executing
"display -$nEigen 0 2"

any help is appreciated. Thanks.

p.s. is $dAmp supposed to be the amplification factor for display?

for what I know "display" is not a simple command, but is used with a recorder of type "display", something like this...

Try to look among the examples and use the script DisplayModel3D, with the other DisplayPlane. It's a good tool to look at the model deformed shape or modeShape.
