postChannel works fine on tutorial case. Also it works on a half-channel (2 blocks in y direction), full channel 4 blocks (ordered in y direction). I tried it on half-channel (1 block) and it gave me the following error:

error message reproduced on channel395 tutorial
to reproduce the error message on channel395 tutorial: (1) make a channel of one block. blockMeshDict (2) remove boundary file. (3) replace 0 folder with a copy of 0.org (no mapFields related issues). (4) run and write 5 times step. controlDict (5) run postChannel related threads: 1 Thanks. Best regards, Maka. |

Problem solved.
That error message was due to a mismatch between postChannelDict entries and the blockMeshDict. postChannelDict requires entering the no cells in each block (blocks are only allowed normal to y direction), manually and it does not read it automatically from the mesh. It is typical that you change the grid resolution or number of blocks in blockMeshDict and forget to update the postChannelDict accordingly which results in either bad collapsed profiles or the above error. Best regards, Maka. |

I solve the problem... I download the OF patch (OpenFOAM-1.5.x) and after remake all, postChannel works fine.
The problem was in the postChannelDict, infact the new version is a little bit different. Best regards MT |
