Hi experts,
I wanted to solve a simple flow over cylinder problem non-dimensionally in acusolve. I understood the theoretical concepts associated with non-diemensionalization. But, I don't know how to implement it in acusolve. Is it possible by just changing the Reynold's number of the flow? If yes, how to do it?
Thanks!

Reynolds number = ( Density * Velocity * Length ) / Dynamic Viscosity
For a given length, you can change the Reynolds number by changing the other parameters, including material properties. For example, if you set density = 1, velocity = 1, and use a reference length of 1, you can set the Reynolds number by setting the appropriate viscosity value.
You'll need to create your own fluid material model in order to specify the density and/or viscosity.
