Mesh Control_Volume Mesh_Parameter
Hello experts,
I am working with 'mesh control' in HyperMesh to meshing for CFD problems. (using BL+tetra)
In Volume Mesh control: BL+tetra, there is a parameter named 'Final layer height/base ratio'.
I searched for help in Hypemesh help home 2019 and the result is found as below image.
<?xml version="1.0" encoding="UTF-8"?>
But i am wondering, how this parameter affect the mesh since the 'final layer height' is already depended on '1st layer thickness', 'growth rate' and 'number of layers'?
My understand for the total thickness calculation is drawn as image below.
For example: Ai = layer thickness, growthrate = 1.2, number of layers= 3.
I also tried some meshing in Hypermesh with large value for 'final layer height' (5 to 10) but no difference b/w cases.
Can you guys give me an explanation? and also correct if i am wrong.
Thanks you very much!
