TL;DR: Enable the use of OpenFOAM as a solver for CFD, FEA, etc by leveraging Fusions modeling and simulation environment to act as a pre and post processor (this will simultaneously fulfill a number of requests/ideas as listed below).
It appears that CFD is already in the works (awesome sauce Autodesk!) for being integrated into Fusion. There is also other software solvers out there that may prove beneficial in allowing Fusion to leverage those assets. Similar to how NASTRAN is used in multiple platforms (Femap, AD, SW, etc). What I propose is the ability to use the tools already in Fusion to generate the model, mesh the model, and view the results from an external solver. In this case: OpenFOAM.
OpenFOAM, as I'm sure you're aware, is a pretty powerful solver in its own right. Out of the box you can do multiple liquids, solids, and gas interactions (I believe there's even codes out there that do eletromagnetic and nano-scale analysis, but I could be mistaken on that front). It even allows users to create their own solvers using conservation equations. Here's a link to it: https://openfoam.org/
There hasn't been much headway into getting OpenFOAM on windows platforms until recently. As of my last check there are a number of windows based platforms available either natively or using Docker. If AD can swing it: Maybe pulling a linux based version on to your servers for users to send their models to for processing, and then getting the results sent back to them?
For running OpenFOAM locally it could be as simple as creating a file the user can put into the program themselves, or if possible, write a process which does it for the user and pulls the results once done.
OpenFOAM has a nice ability to descritize a model into logical processors rather simply: The user inputs how many processors to allocate to the solution and OpenFOAM divides the model into boundaries for simultaneous solving. That would work well with the idea for leveraging parallel computing as suggested in the link below. Maybe with a little AD magic the GPU could be leveraged through CUDA and the like.
A similar model could be used to leverage some of the freely available NASA solvers that are out there too.
