running in parallel, at time t>0
 
I'm running a simulation in parallel, but I need to do it in two parts with a change in BC, and solver, etc.

So, the first bit is easy, I use:
------
deconstructPar
run solver in parallel
reconstructPar -latestTime
run specially written function, changes bc, etc. Now at time latestTime+0.1
-----

My question is how to cast the information of bc, pressures, new U etc at latestTime+0.1 back to all my deconstructed directories, so I can run:
-----
newsolver in parallel


I couldn't find this answer, but I'm not quite sure what to look for, so thanks for help.

Hi all,

i decomposed the mesh ran it in parallel and while doing
reconstructPar -latestTime or reconstructPar i am facing following error.

Please help me in this context.
