I want to capture the velocity field in single phase flow for a domain and then use it for initializing my multiphase flow in the same domain. How can this be achieved? Is there a way to capture the vectors (or velocity data in any form) and write some type of data file that can be read back when I start my multiphase solver?

I found this thread, but no-one seemed to have an answer then? Can anyone help me now?
how to erport one phase date in two phase flow

Thanks,
Pranab

This question was asked by another gentleman a few years back too, but seems no-one had an answer. Well, I asked one of my colleagues in the lab here, and he had a very good suggestion to make.

To get the velocity/pressure data at every node from a steady state or a single phase case, write it as an "Interpolation file" with the extension [.ip] once you have your solution. Then you can read this .ip file back into your two-phase flow field after you initialize your flow field, so that now you have initialized the domain with a velocity field from the steady state itself. This will give better and quicker convergence in unsteady case.

Hope this is of help to someone.
Cheers!
