[Technical] How to know if blockMesh is successful

chenu · August 21, 2022, 08:49

Hello,
Sometimes we execute OpenFOAM and we can read messages from .log file if an error occurs. Is there any way to know if blcokMesh is successfully executed? For example, we could check a value return from OpenFOAM, 1 means some errors occur, otherwise returns 0.
I will be grateful for any suggestions.

Not a bad idea, I dont know of a return value. But looking at my logs, all aplication parts of meshing (blockMesh, snappy, reconstruction, surfaceFeatures, ...) write "End" to the end of the log. I think if some critial error occurs, it will be "FOAM EXITING". Then, can you just look into the log from a script and catch the case when there is no "End" statement and assume something went wrong?
