I am new to CFD and researching options for my employer. We are small and don't have a lot of resources to dedicate to learning and employing CFD within our projects. I am looking for recommendations that would make sense for our needs.
  • Main need is for the simulation of water through a closed system that is then sprayed through a nozzle onto an open to atmosphere curved surface. The surface will be made of porcelain or plastic with the rest being the same.
  • We would need solid software support to help get us through issues we may have. There is not a lot of time for us to experiment with different physics.
  • Accuracy matters, we are simulating pressurized water going through a nozzle and spraying on a surface that needs to be cleared of debris.
  • We use Creo as our CAD tool, so integration would be a plus.
  • Low simulation times are a big plus, as in maybe a day. I know this is very hardware dependent, so suggestions on hardware are welcome as well. We don't have any high end machines.
  • I would like to be able to do side by side comparisons to evaluate what each change does to the flow.

Sorry to be a little vague. I can expand on the application but it's a new product line and I'm trying to describe as best I can without saying too much.

I have been looking at ANSYS, FLOW-3D, Autodesk CFD, and getting the work contracted out. It's hard for me to distinguish what is good and what is bad between them all. Thank you.

I am using ANSYS for my simulation. It worked very well for the problem that you have mentioned. you should need HPC to increase your computation speed.
if you need further details please post here.
