I struggled on this, with bits of (outdated) information scattered all over the place, so here is a brief tutorial, any comment, correction, improvement is welcome!
In OpenFOAM v9 let's consider tutorials/compressible/rhoPimpleFoam/RAS/mixerVessel2D. There we have the following geometry where the rotation of central region is modeled according to MRF approach (but AMI would be the same for our sake). ![]() The question is: what would be the momentum required to sustain the rotation of the stirrer at the specified velocity? To get that we need to add the following lines in system/controlDict Code:
functions { forces { type forces; libs ("libforces.so"); patches (rotor); CofR (0 0 0); executeControl adjustableRunTime; executeInterval 0.01; writeControl adjustableRunTime; writeInterval 0.01; } }; |
