Hi all,

I have been stuck for quite some time now with some mesh that I have been trying to do.

The mesh is pretty simple, a wedge composed of three blocks (solid, heater and fluid in this case) all stacked on top of each other, as can be seen in the picture below.

The red thing in the middle of the domain is the heater (a very thin plate on top of the solid region, and below of the fluid one).

As I said, the meshing is fine, it all comes up nicely etc. My problem is when I put the patches to merge in mergePatchPairs. I keep getting the same errror over and over again and I don't know what to do...

The error (supposedly a geometric one) is as follows,

--> FOAM FATAL ERROR: (openfoam-2106 patch=211215)
Bad points0 0 0.0010005) (0 0 0.0010005) (0 0 -0.9989995)

From void Foam:lane::calcFromEmbeddedPoints(const point&, const point&, const point&, const char*)
in file meshes/primitiveShapes/plane/plane.C at line 108.

I have checked my geometry a thousand times, and I have read everything I've seen online, but to no avail. Could anyone help me please? I'm leaving the blockMesh file below so feel free to try.


Thank you very much in advance.
