I did the simulation again with a RMS residual target below 10^-6 and auto timescale with a timescale factor of 10. The .out files are attended 28450

It seems that the solution did not change a...

I specified the flow as a constant velocity over the cross section. In this case, I think I don't have to halve it.

I actually placed the wrong picture in the first post. The profile is different for both symmetry boundaries.

Hmm, you mean the vectors in the pictures below?...

Hmm, you mean the vectors in the pictures below? The flows are different but 10^-3 to 10^-4 less than the primary flow. Does this have a effect on the primary flow?

Maybe I don't understand the...

This simulation is just about a straight rectangular duct to obtain the velocity profile. The profile will be used as initial condition for an inlet of a microchannel with different geometries, so...

Thank you for your reply. All simulations...

Thank you for your reply.

All simulations converged with a RMS Residual Target below 10^-5. I've done a mesh sensitivity study. I set up different meshes with unstructured tetrahedral objects with...

Different results with Symmetry

Hallo Everyone,

I simulated a rectangular duct one time with and one time without symmetry boundary. I just wanted to obtain the velocity profile at the cross-section of the channel. But the...
