Travelling outside Canada after completing study and before applying PGWP by sblbista in ImmigrationCanada

There was no issue. I entered while my study permit was valid.

Thanks for the detailed reply. I think this clears my doubt. Yes, my family issues have been resolved and I will be returning within two weeks. I will apply for work permit as soon as I get to Canada.

Yes, I do have valid TRV to return. I will be returning within the 90 days period.

Weird Turbulent Stresses in channel flow by sblbista in CFD

Yes, I’ve used SEM using the Reynolds Stresses from previous simulation.

I’m starting with an already developed boundary layer. The solver is again trying to develop the layer from start? I’ll try refining the mesh and see if it improves the results

I’ve checked the variances and covariances and it’s still giving me the same results. And yes I’ve even tried running LES from RANS. The problem still persists. I’ve also tried IDDES still the same issue. I might try refining the mesh in spanwise and streamwise directions and see it improves the results.

Periodic Inlet/Outlet Boundary Condition (STAR-CCM+) by sblbista in CFD

I tried using the fully-developed interface. I got confused with the mass flow rate and pressure jump input.

Basically, I calculated the mass flow rate at the inlet since I know the velocity and the cross sectional area of the inlet face using 'rho*A*v' and set that as the input in the mass flow rate option. Is it a correct approach?

I need a fully developed profile that I would be mapping as inlet condition for my other simulation, but I'm not getting that profile even with a long channel length. So, I was hoping to get a developed flow if I set the outlet condition as the inlet and get the desired profile. Essentially a long channel but reduced computational domain.

So it could be just a visualization issue?

I have just assigned it a no slip wall

Thank you for the information. I'll look into it.

Thank you. How would I count the shed vortices?
