failure with parallel computation with WENO #41
-
|
Hi all, I encounter a problem with using the WENO scheme. I ran the tutorials well with the scheme in parallelization. However, when I ran a case in parallelization with a mesh generated by myself, it always failed with the following error. But it works when calculating with a single processor.
Kind regards, |

Dear Zhenlong, did you use the master branch? I have made some improvements on the development branch to fix these kind of issues especially when you use collated file I/O option in OpenFOAM. The version on the master branch requires that the case is decomposed with the uncollated format and that the processor directories can be read. The new version on the development branch circumvents this by actually sending the mesh information over MPI to the required processors. This has two advantages,
In summary, please try out the development branch :) |
