I performed a case which time ranged from 0s to 200s with sparse grid(192000 cells) on 4 processors.

Then, a geometry with better grid(576000 cells) and same BCs was established.

Code:
mapFields -consistent <dir>
required so much time, I'd like to execute mapFields with parallel mode.

Code:
mapFields -consistent <dir> -parallel
or
Code:
mpirun -np 4 mapFields -consistent <dir> -parallel
have been tried and failed.

Is there someone knows how to speed up mapFields with parallel mode?

My OpenFOAM is 2.3.0.

Thanks in advance.

hello,
There is a lot of change in the mapFields for 2.3. (and we lost the ability to map from single to parallel case and the opposite).
If you want to keep the old map method (faster), use option "-mapMethod mapNearest".
But for me there is a regression with mapField, so i use the 2.2 version for this tools.

regards,
olivier
