I am doing a 2-D mesh of a speaker which have a diameter of 6.5 inch ，and the minimum mesh size is 0.0125 mm, I split the speaker into many parts in order to do the mesh easily but the smallest part cost me 1 hours and the biggest part can cost almost 4 days. Does it regular? It's just 2-D model. Or I did something wrong.

anyone can help me thx !

What you are trying to do?

Either LES or URANS? If yes then what is time step and total mesh size.

What are the machine specs on which u r running the simulation?

I think 2D problem should not take more then a day for quad core processors with reasonable RAM.

I am going to compare the result of the simulation by three cases, the mesh size of these three cases are 0.025mm, 0.0125mm, 0.00625mm. But I failed to do the mesh of case 3 because the mesh cost so much time.
this picture I have uploaded is the model .
I use the computer in my lab and its good, so we don't need to consider about the machine.
The elements of the mesh in case 2 is 1139244 .

thank you for your reply

Thank you for your reply. I have solved this problem by Gambit.
