I suppose this is coming at some point.

I hope so. I had quite some success with the rocket fast CFD Ansys implemented in Spaceclaim, which I used before Onshape. Getting an idea (and visualisation!) of what is going on in or around our designs is already important in the very early stages. Everything sorted out then is less likely to drop onto our feet later. No time to wait for external results or even go through the hassle of communicating the design with external teams.
@martin_kopplow "the hassle of communicating the design with external teams." This is a major headache. Glad its not just me thinking this. Yikes!

… and the lead times. I've been working with Volkswagen at the time and they had their own sim team. I was required to have every design change analysed by them, but I had tight deadlines, too. So after changes were agreed upon in a meeting, I went back to my office, made the changes, ran a CFD on my actual CAD data*, compared with before the change, communicated the visuals same day and got approval. That meant I could get on with my work, and when simulation results fom the client team arrived a week later, they were usually within a low one digit percentage affermative. Also, I would run a CFD over my propsals for a change to evaluate variants and then support my proposal and get immediate approval right in the meeting. A real time saver. Imagine I had to wait a week until I got the simulation results, and only then get to work at it.
I am not doing much CFD related stuff recently, but I'd like to, if I had the tools.
*…which is actually the magic sauce here: running the analysis on actual CAD data without keeping a separate strain of exported data up to date.
@martin_kopplow , fantastic story, you should make a video for Youtube as i like watching videos about such stuff.
@digitalcarbon , people do sure like watching videos, but making good videos requires time and effort, besides a sample project that is not under any NDA. So … not likely to happen anytime soon. ;0)
