Excessive 'cacheAgglomeration no;' for moving mesh cases in tutorials
Functionality to add/problem to solve
The GAMGAgglomeration automatically is deleted at every mesh movement/topo change so there is no need for disabling the cacheAgglomeration
if
- agglomeration based on geometry only (= default,
faceAreaWeight
)
E.g. run incompressible/pimpleFoam/laminar/mixerVesselAMI2D
case with/without cacheAgglomeration:
mpirun -np 4 pimpleFoam -parallel -debug-switch GAMGAgglomeration=1
and you'll see that even with caching it still gets recalculated. With caching off it will re-agglomerate for every pressure solution. Note that it is different for matrix based agglomeration - there even multiple invocations of the GAMG might want to use different agglomerations.
