Default How to corse mesh in icem cfd?
Posts: n/a
I have to at persent work in icem on one proj in my comapny. Its mesh size is going to be very high in term of millions. I have to reduece that mesh size. I know icem but i am finding these difficulties.

First is that how i can reduce no of elments. I think one options is by increasing mesh elem length as well as scale factor?. I am talking about Unstructred mesh.

Second i have also gone thru node spacing on curve.but it is not reducing mesh at all !! is there any other way to reduce no of elments. Quality criteria is not that much imp for me.

suppose we have one surface and we have done mesh then can we reduce no of elments?

Can corse function in volume mesh reduce no of elments?

Pls suggest me any suggestions to reduce no of elments. Quality criteria is not that much imp for me .

Thanks and regards Priety.

Increase the scale factor. A factor of 2 roughly reduces the mesh size with a factor of 8.

There is a function under Mesh Edit (Tool symbol: two parallel green rectangulars devided in tet elements) where you can coarsen/refine your mesh. Good luck. TobiasZ
