CFD Softwares with CAD integration

han toss

Hi,

I am planning to look into CFD softwares that are directly integrated with CAD softwares. I have heard most of the people say that this is the way to go for now and the future as it reduces unnecessary re-making of the geometry and also offers automatic grid generation.

On the other hand, some people say that there are some strict standards that the CAD designer has to maintain in his/her part and assembly models to be able to export these into the CFD module for fluid flow analysis. For example, there should be no volume interferences or gaps in the CAD model. My models ususally are pretty error-free, but if they were not, would it cause problems with the CFD module?
