Flow Rate Boundary Condition

The simple flow rate can be prescribed at the inlet. Its fixed value is equal to massFlowRate.

Running Simulation - Parallel Run - Domain Reconstruction

When simulation has finished data needs to be reconstructed:

# reconstructPar -region spiral > log.reconstructPar.spiral
# reconstructPar -region rotor > log.reconstructPar.rotor
# reconstructPar -region drafttube > log.reconstructPar.drafttube

 

#!/bin/sh
reconstructPar -region spiral -latestTime > log.reconstructPar.spiral & 
reconstructPar -region rotor -latestTime > log.reconstructPar.rotor   & 
reconstructPar -region drafttube -latestTime > log.reconstructPar.drafttube

Message Passing Interface (MPI)

For parallel computations there is Message Passing Interface (MPI) standard used. For more details see e.g. [13].
