I am very new to using Altair Hypermesh. I apologize if this is a novice question.
1. I have a complex model in .stl format. Can I extract all the nodes on the outer surface of the model? If yes, then how can I do that?
2. Can I import a .vtk file?
What do you mean 'extract all the nodes' ? You want to get NodeID & coordinates? STL will be imported into Hypermesh as a FE mesh. So you can export STL (nodes and topology) to any supported solver (Nastran, Optistruct, Ansys, Abaqus,...).
Via FE output template, you can export to any output format.
Yes. I do want to get NodeID and Coordinates but I want to get the nodesID and Coordinates of only a specific surface.
Try this simple code:
*createmarkpanel nodes 1 'Select nodes' set nodeList [hm_getmark nodes 1] set output 'C:/Temp/nodes.txt'; set fh [ open $output w ]; foreach nid $nodeList { variable x [hm_getvalue nodes id=$nid dataname=globalx] variable y [hm_getvalue nodes id=$nid dataname=globaly] variable z [hm_getvalue nodes id=$nid dataname=globalz] puts $fh [format '%6d %12.4E %12.4E %12.4E' $nid $x $y $z] } close $fh
Adapt 'output' to your output file.
