Select outer nodes on cylinder
Hello,
im doing Modal Analysis of a stator (which is basically a cylinder) in Hypermesh. The model has around 700000 nodes. The analysis results are output in a pch file. The problem is this file gets really big when i consider multiple modes. I need to import this file in matlab to do some further calculations. So I would like to reduce this file, because I only need the results at the outer nodes anyway. I know which settings to use, but my simple problem is to select the outer nodes. Im looking for something like "selection by cylinder", where I can say everything beyond r=100 mm should be considered. I know there is something like that in the tcl scripting (hm_createmark nodes ....), but there I get the message "In scripts, only the last 100 entities may be retrieved directly". I also tried selection "by face". (I assume) It is not working because my model is an imported solver deck an there are only nodes and elements in my geometry, I cant select any face.

I assume you're working with HyperMesh.
you could use 'by face' for this, with no issue. It is not limited to geometry.
By face works by first selecting some node/element and then using 'by face' to pick the other ones in this face.
If your using HW desktop, Go to your desired operation, click in one node of your outer shell and the click the node selector and click 'by face'.
If you're using the new HyperWorks, then click in 1 node and right click and 'select' >> 'face'.
