This are the setup and running steps: #1. blockMesh --> edit constant/polyMesh/boundary --> edit defaultFaces "empty" to "wall" (i have an issue to define the pipe wall boundary, so i need to edit it manualy) #2. setField #3. decomposePar --> please edit system/decomposePar with your own hardware preference #4. mpirun -np x foamRun -parallel --> set the number of x with the number of core within your decomposePar setting or you can run "foamRun" after "setField" to start running without parallelization
