Centroid of named selection (face) with APDL

[dixib]

Hi,

I'm trying to get the centroid of a named selection using APDL. The named selection can have arbitrary shape, and needs to be found for the deformed shape (at least when large deflection is activated).

I've tried the following code:

cmsel,s,[i]NamedSelection[/i]
asum
*get,CentroidX,area,0,cent,x
*get,CentroidY,area,0,cent,y
*get,CentroidZ,area,0,cent,z

Unfortunately it doesn't work, as post.out states that: "ASUM is not a recognized POST1 command, abbreviation, or macro..."

Is it possible to find the centroid of an arbitrary area with APDL?

Thanks in advance. Your help is much appreciated.

"ASUM" is PREP7 (preprocessing) command used for flat areas only. Refer ANSYS APDL command reference manual.

Remove the ASUM command in above code and may be it can work with *get commands.
