Hi,

I am trying to set up a simulation of water flowing past a 3D object to solve for drag force and lift force.

This seems similar to a wind tunnel like case so I was assuming I could copy a tutorial such as simpleFoam airFoil2D and modify it to be 3D, add my geometry and change the fluid from air to water.

I am a bit stuck as to how I specify the fluid is water.

If anyone has any suggestions on a better way to set up this case I would be very grateful!

Thank you.
