Region Command

[simonkey]

What is the correct way of using the region and recorder commands to obtain the eigenvector values at certain nodes?

I have the following code and it crashes opensees when I run it:

# eigNodeList is a list containing the node numbers desired (eg [100 200 300 ...] )
region 1 -node $eigNodeList

.
.
.

set xrec($index) [recorder Node -file $xname -region 1 -dof 1 "eigen $index"]
