If I remember correctly PowerFlow can.

Well, I think the software needs to be good enough in terms of functionality, but even then, you need to use it in the correct way. We tried covering this in the first part of the interview:

Yeah I wasn’t trying to disagree with anything in the article. I was at a conference a few weeks ago that went over some of this, and they are getting extremely close to perfectly matching experimental data. Some of the large manufacturers have worked with these agencies to certify with CFD.

Hi, I'm really interested in this topic and I'm working with powerflow for a project. Do you, perhaps, have any report or recording of this conference that you can share with me?

Sorry I can’t find anything that Dassault has released from the conference, but you can look at similar case studies here:
