Re: [Eidors Help] Error when using Netgen to build Single Plane Models

[Andy A. <ad...@sc...>]

I have two bits of advice to start.

First, can you find a smaller piece of code that shows the error.
Next, that code is really old, can you try:
    fmdl= ng_mk_cyl_models(1,[],[]);

What does that give?
