reconstructParMesh + GGI problem
 
Dear Foamers

I found a very strange problem when I tried to reconstructParMesh with the GGI results (a rotating propeller). The simulation was run with 128 cores

1st run: the case was run from t = 0 to t = 1. I used the reconstructParMesh to reconstruct the data without any problem. The data was good under Paraview

2nd run: due to the limited hard drive space on the cluster, I removed everything except for t =1 in the processor0 to processor127. the case was run from t = 1 to t = 2 without any problem. Again, I used the reconstructParMesh to reconstruct my data without error. However, the mesh geometry was completely wrong (looks like the node connectivity was lost, points are not connected correctly) :eek:

Did anyone have the same problem before?

Was this because I removed the 0 directory from each of the processor1-processor127 directories?

Should I change the startTime in the controDict as I realise that reconstructParMesh tends to create a polyMesh directory at time - startTime in the controlDict before it does the reconstruction processor?

I really appreciate if anyone used the reconstructParMesh.
