FluentMeshToFoam hangs with no error
 

I generated a hex grid for a free-surface-piercing NACA 0024 using Gridgen from Pointwise, Inc. It is a simple c-type grid with clustering near the wall (for wall fxn) and near the waterplane. However, when I try to convert it, it simply hangs and does not report an error. Any suggestions on how to debug this?

Here is the output:

This is a strange place for the converter to hang: you have successfully finished lexing. Can I have a look at this file if it's not confidential?

Hrv,

You can download the file from:

It is the only file there. Also, I mistyped my original email. This grid was designed for sublayer resolution.

I get a nice core dump over here:

--> FOAM FATAL ERROR : index 6 out of range 0 ... 5

It turns out that the cell number 182, defined as a hex, has got 7 (at least 7?) faces, which is wrong. The offending face index is 976015.

My guess is that you have defined a face of cell 182 to belong to two boundary patches at the same time. As usual, nothing wrong with my converter.

Thanks for the debug, Hrv. I'll double-check, but this would be impossible to explicitly do when using GridGen. Maybe there is a bug with the Gridgen -> Fluent converter, although I've not run into one before. I'll post back when I find the error.
