On the simulation accuracy.
 
Hello everyone, When using fluent to simulate 3D flow field, I find it is difficult to simulate actual flow, it is to say, I caní»t obtain better accuracy. Do the different turbulent models have different effects on the computation results? How do I modify? Mesh? Boundary conditions? Or flow parameters? I doní»t know what I should do. Can you give me any advice? Thank you.

Re: On the simulation accuracy.
 
it is true that the accuracy strongly depends on the mesh and the related turbulent model ,wall treatment. maybe carefully reading the fluent docmentation will be of help for you.
