OpenVSP crashes when doing analysis

[Daniel Summers]

Hi,

First post. I started using OpenVSP the other day.

When running analysis it always crashes. I’ve been trying to use both VSPAERO and CFD Mesh.

When running VSPAERO, it crashes when launching the solver. Looking in the solver tab, it crashes when it starts the 1st wake iteration.

When running CFD Mesh, it crashes when loading Bezier surfaces.

I’m running:
Windows 7 Ultimate
Intel Core i7-4770K @3.50GHz
16GB ram
NVIDIA GeForce GTX 750 Ti 2GB

Error running CFD Mesh:

There must be something about your geometry that these algorithms don't like -- they aren't perfectly robust, but are generally pretty good.

Without knowing your geometry, we can't really make suggestions as to how to fix it.

You might try deleting components  (say 1/2 at a time) to try to narrow down what is causing the problem.

In general, I recommend people start with simple models, building up the complexity gradually.  Similarly, if your intent is to run VSPAERO, start simple, checking how VSPAERO does each step of the way.
