Hi,

Perhaps this is a stupid question, but I excel at those

Are decomposePar and reconstructPar parallel capable? What I mean is, can these programs successfully be run using OpenMPI or similar across multiple processors to speed the decomposition / reconstruction times for parallel cases?

Again, sorry if this is a silly question or if it could be answered by looking at the source of those programs--not a developer, just a tool-user in this case.

Hi!
They are not parallel, but you could consider using redistributeMeshPar, that does work in parallel.

I wrote a basic bash script for running reconstructPar in pseudo-parallel mode as describe in this post. This is only useful if you need to reconstruct a large number of time directories from a transient run.

I have facing problem to run decomposePar in "of220", but it run in "of41". but when i have open paraview with "of220", processors distributed after decomposePar not read the cells...i think....nothing to show in paraview with of220....mostly in case of temperature....average temperature and maximum temperature both are same....plz suggest me solution
