You can try to implement a fluid dynamic simulation for yourself:
See https://mikeash.com/pyblog/fluid-simulation-for-dummies.html
Or you could use fluid/particle simulations part of software like Blender or Cinema4d.
Of course there is professional software like Ansys CFD or RhinoCFD.
But this all doesn’t help you in trying to get shapes out of it. Have you ever heard of a car or airplane design autogenerated by a modified cfd? It is the other way around, you create a shape and you test its aerodynamic using a cfd analysis.
Anything else is a hoax. Don’t trust these things too much.
