Hi Madhi,

It all depends on how you set up the mesh (and its dimensions) and the inflow velocity magnitude. You cannot set rho in the incompressible solver however. Nevertheless, if you are using stabilization then if you use this in real dimensions you may have to rescale this feature too. This is why using non-dimensionalisation can be better for situations where you want to also turn on these features.

Cheers.

Spencer.

Hello NeEKTAR++ users,

I have a simple question. Does NKETAR++ have the ability to simulate real scale models or not?

So far, I always used it in dimensionless form. But for some cases, it is impossible to make the whole model dimensionless. 

Does the code work properly for cases with real dimensions and actual velocities?

Best regards,
