I am creating a mesh of a simple wedge composed by two blocks. The case with another geometry runs well, but when I put my data I am getting the following error.

Any help please?

Thanks so much

One mistake is for sure, that you used nodes twice in hex element 1:

hex (1 4 3 0 6 8 3 0) (34 112 1) simpleGr

[veronica2015]

I have done that in other simulations and it has not been a problem. It corresponds to the first block that is a triangle.

If you need a triangle take one: OF offers triangles.

If you mesh this way cell faces have zero area.

What shape are you tying to apply wedge on? I could make that in gmsh quickly. Just provide your dimensions and it should be easy.

Cheers,
