Hi Foamers
I am trying to do LES of a diffuser like as in Eugenes Thesis. To get grasp of mapped inlet at first I am testing just a plane channel. I map a plane in midway back to inlet with zeroGradient outlet. The blockMeshDict reads type mappedPatch; offset (5 0 0 ); sampleRegion region0; sampleMode nearestCell; samplePatch none; and the 0/U reads velocity_inlet { type mapped; value uniform (20 0 0); interpolationScheme cell; setAverage false; average (20 0 0); } The case runs. But the mean values are very less like 1/100 of what I specify i.e. 20m/s. What can be the reason? Thanks |
