Hi

I'm trying to make a hybrid blocked/tet mesh in icemCFD. I create a blocking, and change the type of blocks I want to contain the unstructured tet mesh to "free". My problem is that the unstructured mesh in the free block does not conform to the surfaces within that block. Does anyone know how to make this the case?

For reference, the attached images show a simple geometry (sphere in a box), a tet-mesh of the whole gometry, and a hybrid mesh computed by setting the centre block of an o-grid to type "free". Note how the hybrid mesh does not confirm to the sphere.

Many Thanks
