ICEM CFD Tetra mesh is of a very high quality. A high percentage
of volume cells are near perfect TETS.
The above image shows a cut-away subset of an engine manifold. The quality is displayed in three ways.
1) Mesh Color by Quality
2) The Message window shows the number of elements within each range
3) The Histogram chart shows columns in each quality range, it also lists the minimum quality as 0.12. This is good enough for almost any CFD and FEA solver.
