Hey,
I am using sonicFoam on OF 2.1 and when I would like to calculate the Mach number in my domain I simply run Code:
Mach However, this is tedious and also problematic when I examine a running case via paraview, because I would have to run Code:
Mach -latestTime Is it possible to tell OF to calculate the Mach field at every write interval during runtime? I have already tried to add a Code:
systemCall writeCalls 1( "Mach -latestTime"); Code:
controlDict This should work for composed cases but won't work very well when running in parallel, since I would have to hardcode the root directories for each instance. Am I missing something? Is there a better way? |

Functional objects can be added to the controlDict, such as:
Code:
functions { MachNumber { type MachNo; libs ("libfieldFunctionObjects.so"); executeControl timeStep; writeControl writeTime; } } |

Hey All,
if you need the MachNumber only for last iteration, (or for old simulations) you can also create a new controldict file (such as postDict), with all the standard entry and the functionObjects and run "application -postProcessing" Cheers, Carlo |
