[ICEM] Which topology is better.

Far · October 31, 2012, 06:21

Hello

I am comparing the two topologies for the Ahmed body mesh and want to know your opinion that which topology is better: Topo1 or Topo2 and can you tell me how to create both topologies and why such difference is there even overall idea is the same.

Topo1

Topo2

Would the best topology (for this and any other Hexa mesh) only be determined by:

1) the mesh quality metrics.
2) the accuracy and mesh insensitivity (when the number of nodes are altered on the topology) on the CFD solution.

For both meshes min quality is 0.8-0.82 and min angle is 38-42.
