Dear all,

it might be a very stupid question: I am trying to mesh a wind turbine and the flow field around it. The flow field is a sphere of 900 meters of diameter. I am meshing it as unstructured volume mesh, robust octree.

I am using ICEM 14.5 on a ASUS with 16GB of RAM with i7 with 3.4GHz.

However, every time I try computing the mesh, the programme generates 100,000,000 tetrahedra (48% of the process) and stops there.

Is this problem related to the computer (not powerful enough), or there are some settings on ICEM which defines the maximum number of elements/nodes? How can I increase them if there is?

Thanks a lot,
Best

Dear friend you can increas the size of the cell. On the mesh tab, click on the global mesh parameters and there you will be able to change your mesh size criterias... good luck!!!
If you define those values as zero (0) the mesher will define a "good value" as a recommendantion...

You should calculate rough sizes for different parts and apply them via part mesh setup. Also you should set the proper mesh sizes in global mesh parameters.

If you want to have refined mesh in wakes, use density regions.
