Random path plots for element table quantities in ANSYS APDL
Random path plots for element table quantities in ANSYS APDL
(OP)
Hello everyone,
In the attached images, there are 3 surfaces- spherical calotte, cylindrical roof and hypar. I want to define paths along the lines on these surfaces to plot element table quantities. The size of these surfaces is 10 meter x 10 meter and the element size is 50 mm. It is difficult for me to go around the surface to select the nodes one by one.
Can I define lines, arcs through modelling tools (in pre-processing) and then select these lines/arcs as the paths? Or can you suggest another way of doing this task.
Also, I have material discontinuity in the model but the path plot doesn't show the expected jumps in bending stresses at material interface. Is less number of points and divisions on the path a possible reason for this problem?

Get in the habit of exploring the detail for a tree item when you get stuck. Most of the items in the detail have hidden scroll-downs with multiple options.

Thank you for the reply. I am basically working with APDL. Can I do the same operations in APDL?

endkp=26 ! this is the number of the keypoint at one end of the path
lsel,s,... ! select your lines

ncount=ndinqr(0,13)

*if,j,eq,1 then
nnum=node(kx(endkp),ky(endkp),kz(endkp))
*else
xx=nx(nnum)

I tried your script. It returns a warning message 'No path data active. PPATH command is ignored'. Do you know what's going wrong here?

I read about PATH, PPATH and PDEF commands. I am using Path operations > Define Path > On working plane > Circular path option > x and y coordinate and circle radius. This requires adjusting the working plane origin to center of sphere (of which the spherical calotte dome is a part) with different plane orientations.
Thanks for your help.
