Hello forum,
I did a run using a hydrid grid (prismatic layers at walls, and a fully tetrahedral mesh at the fluid domain interior). The mesh engine is custom.
SU2 tells me, about mesh quality:

+--------------------------------------------------------------+
| Mesh Quality Metric| Minimum| Maximum|
+--------------------------------------------------------------+
| Orthogonality Angle (deg.)| 51.2934| 89.7623|
| CV Face Area Aspect Ratio| 1.75245| 655.572|
| CV Sub-Volume Ratio| 1.01781| 5.38083e+08|
+--------------------------------------------------------------+

The last parameter has a very high maximum value: 5.3E8.
The solver starts and exits with residual divergence after a few iterations.

Question:

supposing the volume mesh is well defined (no intersecting elements, ...), in your experience could these very streched elements lead to this divergence, in a few iterations?

Thanks a lot
Giovanni
