Hang Yi

Hi Ben，

I think it is not for you to find an internship for CFD fundamentals studies, because they want you to do some topics. While there are many topics in ANSYS student community. I do think you can find a lot items you want to learn. Thanks.

Ben Tra

Mr Hang , I thank you very much for your answer, but I think I was not clear enough. the subject is to find a laboratory that works on the energetic "mechanics of fluids" which could allow me to use its means of research in the field
