Hello. I've been running a simple 1D traveling wave case using scalarTransportFOAM recently. The mesh is N=80000. When I tried to sample the data, the log.postProcess kept running on creating mesh at t=0 but without any other progress. The log file is below:

Create time
Create mesh for time = 0
I tried to reduce the mesh, and I found sampleDict worked quite well for N<8750; for N>8750, the sampleDict could not have any results but just kept the 'create mesh for time = 0'.
Are there any solutions to make the sampleDict work on large mesh?
