2 Synopsis

PDRMesh [OPTIONS]

3 Description

Mesh and field preparation utility for PDR (porosity/distributed resistance) type simulations.

Reads

• cellSet giving blockedCells
• faceSets giving blockedFaces and the patch they should go into

NOTE: To avoid exposing wrong fields values faceSets should include faces contained in the blockedCells cellset.

• coupledFaces reads coupledFacesSet to introduces mixe-coupled baffles

Subsets out the blocked cells and splits the blockedFaces and updates fields.

The face splitting is done by duplicating the faces. No duplication of points for now (so checkMesh will show a lot of 'duplicate face' messages)

The parameters must be specified in system/PDRMeshDict. The example shipped with the source code (in $FOAM_UTILITIES/mesh/advanced/PDRMesh/PDRMeshDict) is reproduced below.

-overwrite

Overwrite the existing mesh files

-parallel

Run the utility in parallel

-roots "(DIR1 [...DIRN])"

Directories through which the data are distributed

-case DIR

Execute the command on the case directory DIR. If not provided, use the current directory

-noFunctionObjects

Skip the execution of the functionObjects

-help

Display the help and exit

This utility is used in the following tutorials:
