Hi,

I have simulated pipe flow separately using perturbU code.

I want to take snapshots from this run and give it as inlet condition to another LES simulation. I have saved those velocity snapshots in files U0, U1.....

I don't know how to make OpenFOAM solver run one snapshot every iteration so that variable velocity is fed to the LES simulation.

I have tried it using codedFixedValue but it doesn't work in parallel.
Segmentation fault when trying to run in parallel

I know that no boundary condition exists which can do this.
But which existing boundary condition would be suitable for developing new boundary condition?


Can you please help me with this?

Any suggestion is welcome.
