Find corner nodes of a mesh
Altair EmployeeHey guys,
do you have an idea what the best way is in order to find corner nodes of a curved mesh? I want to find the yellow nodes automatically by using a tcl script.
A few hints would already be helpful. Thank you for your help.
Cheers,
Mike

Altair EmployeeHey Tinh,
thank you very much for your help! :-)
Cheers, Michael
Hi, there are several ways to do. below are some hints for you (suppose that you isolated only this comp)
- the node is belong to only 1 elem, so you can loop through displayed nodes, and check number of elems attached, by *createmark elems 1 'by node'
(this loop is long if your comp is big, so use a template code is better than tcl)
- the node is on free edge (feature), and at breaking angle ~90D, so you can create feature with beaking angle 80D, search for nodes nearby breaking points (ends of feature lines)
- create a surf 'From FE', the nodes will be at fixed points of surf
- get geometry box of this comp and search for nodes nearby corners of geometry box
