Re: [ff3d-users] Problem in the dx operator.

[Stephane Del Pino]

Hello.

Thanks for the report. It seems that there is still a bug in the interpolation 
algorithm for unstructured hexahedra meshes : when no point is found inside a 
mesh the function value is 0 which appends for your function g, then f/g goes 
to nan.

I have no time to go for it now. And I don't know when I will...

Again, if you *really* (I mean *really*) need it you could try to fix it and 
then give back to ff3d community your fix. But I again do not understand why 
you cannot cut your hexahedra mesh into tetrahedra which works really better 
with ff3d: much faster and I think not buggy...

Best regards,
Stéphane.
