Thank you Dekeyser.
You are close, but it’s usually OpenFoam that’s the problem. OpenFoam is an open-source Computational Fluid Dynamics solver. It has a proven record, but the makers have not been exactly bending over backwards to support Windows. AFAIK, OpenFoam may be intolerant of spaces in a user name, that’s why I wanted to check with an account named “CFD” . The alternative to OpenFoam is Fluent, which costs some $30,000 a seat, per year.
What upset me, as a user, is the license manager in V6 has generally become more restrictive and cumbersome, and it is reporting false-positives, which will likely be used as a persuasive argument to make Rhino 3D more restrictive, in an big ugly cycle or long-loop.
As a company, McNeel, has been good company, with a supportive staff and historically fair licensing. With very few exceptions Rhino 3D has a remarkably wonderful web-forum. As a product, I love Rhino3D, and there’s not a lot of other software products that I can state that about, and I just don’t want that to change.
