Import results from a different simulation as a boundary condition or solve simulation for each geometry separetly

Hi folks,

I am simulating a pipe flow with 2 sections, and due to the dense mesh, the cluster is running out of memory.

So I was wondering: is it possible to simulate the first section and save the results, then later on import the profiles from this simulation into another file?

I just need the profiles at the pipe exit so I can use it as a boundary condition in the inlet of the second pipe.

Edit:

Another option would be to solve for each geometry but not at the same time, in other words, solve for the various
geometry parts but one after the other.

Is this possible or something similar?

Best Regards,
