Hey 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

    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
