if no of cells in the direction that we decompose over is not dividable by no of processors. decompose Par works OK but we get the following error when running.
To reproduce the error: ------------------------- tut; cd channelOodles/channel395 rm -r 0; cp -r 0.org 0; modify blockMeshDict to have 63 cell in x direction. decomposePar with : method simple; simpleCoeffs { n (2 1 1); delta 0.000001; } nohup mpirun -np 2 channelOodles .. channel395.50 -parallel; To remove the error: ----------------------- make no of cell 64 in x dir. -------------------------------- DECOMPOSEPAR OUTPUT: Time = 0 Create mesh Calculating distribution of cells Selecting decompositionMethod simple Finished decomposition in 0.27 s Calculating original mesh data Distributing cells to processors Distributing faces to processors Calculating processor boundary addressing Distributing points to processors Constructing processor meshes Processor 0 Number of cells = 47250 Number of faces shared with processor 1 = 3118 Number of boundary faces = 4996 Processor 1 Number of cells = 47250 Number of faces shared with processor 0 = 3118 Number of boundary faces = 4996 Processor 0: field transfer Processor 1: field transfer End. ---------------------------------------------- ERROR MESSAGE: Create time Create mesh for time = 0 [0] [0] [0] --> FOAM FATAL ERROR : Cannot find patch edge with vertices (11 1630) on patch procBoundary0to1 Can only find edges 4 ( (11 86) (8 11) (11 14) (10 11) ) connected to first vertex [0] [0] From function processorPolyPatch::updateMesh() [0] in file meshes/polyMesh/polyPatches/derivedPolyPatches/processorPolyPatch/processorPolyP atch.C at line 351.

I followed your steps but cannot repeat your problem. You are running 1.4.1 I hope?

no. I'm using V1.3. Was there a problem in that version? I do not know if it is too much to ask you what are the files that had the probelm (decompostPar only or others). Sorry, to move to 1.4.1 I need to do lots of testing. I will do it as soon as I can. Thanks Mattijs.
Best regards, Maka. |

By heart: check processorPolyP

By heart: check processorPolyPatch.C and coupledPolyPatch.C for differences between the two.
