I am facing a problem of mapFields taking too long to map fields from a fine mesh to a coarser mesh. I am running simulation using sprayFoam, and want to coarse the mesh to achieve faster solution. So I executed:

Code:

mpirun -n 4 mapFields ../aachenBomb-fine -sourceTime latestTime  -consistent -parallel

in the aacheBomb-coarse directory and it is running without errors. However, it gets stuck at here for four hours:

Code:

 Create meshes

Source mesh size: 42025    Target mesh size: 42025


Consistently creating and mapping fields for time 0.0004

Creating mesh-to-mesh addressing for region0 and region0 regions using cellVolumeWeight
    Overlap volume: 4e-05
Creating AMI between source patch walls and target patch walls using faceAreaWeightAMI
    AMI: Creating addressing and weights between 19762 source faces and 19762 target faces
    AMI: Patch source sum(weights) min/max/average = 1, 1, 1
    AMI: Patch target sum(weights) min/max/average = 1, 1, 1

Anybody knows what is wrong?

kind regards,
