Hi,
I created custom velocity inlets for a) linear shear flow b) logarithmic velocity profile to use them with pisoFoam. For testing I run the following commands: 1) ~>decomposePar 2) ~>mpirun -np 4 pisoFoam -parallel -case . 3) ~>pisoFoam -case . In the case of the linear inlet (a): 1-3 run without error In the case of the logarithmic inlet (b): only (1) and (3) run running pisoFoam in parallel however fails with the error message below. The corresponding section in the velocity 0/U: ... inlet { type logVelocity; n (1 0 0); y (0 0 1); uStar 1.0; z0 0.1; kappa 0.41; //value uniform (0 0 0); // for paraview } I dont know where to search for the error, as my configs/custom libs run fine in the serial case. When checking the processor0 - processor3 directories I found that the kappa entry was missing in the U dictionary. After adding the entry manually I succeeded running the case Hope somebody has an idea why decomposePar omits the entry Thanks a lot hj ----------------------------------------------------------------------- ...
