path definition APDL

path definition APDL

path definition APDL

(OP)
Hello!.
I am going to look at total deformation on a line. The path I can define is for undeformed shape but I want to
define it on the deformed shape. This is for a non linear buckling analysis.

I was trying to use the UPCOORD command to update the coordinates, to compute the new position using x'=x+UX, then I put
the x',y' and z' for the path using PPATH, and when I tray to do pdef APDL says: "the requested data is not available".

I need some help to end this problem.

Regards!

RE: path definition APDL

Hi SebaMorgado,

I needed this once i did the following:

Name nodes before you solve, then you can use them later in the path operation:

nsel,all
csys,0
N1=node(x,y,z)
nsel,all

then you can use N1 in ppath:

PPATH,1,N1

Hope this helps,

bram
