Hello everyone, 

I have a recurrent problem when meshing with SnappyHexMesh: there are "holes" on some boundaries of my mesh (see picture). Do you know why this is happening? And what could I change to have a mesh that perfectly match with my geometry? I am working on a passage of a centrifugal compressor. 

Thank you in advance !

Hi everybody, 

I ran a steady state + transient CFD simulation on a centrifugal compressor (with a k-omega SST model) and when post-processing the results and comparing the stationary part to the unsteady part of the calculation I have significantly different results. Indeed, the unsteady part shows a higher mass flow rate. This seems to be due to a higher flow speed and a...

Hi everyone,

I woud like to export the relative velocity URel magnitude, instead of the absolute velocity U magnitude, in the interfaces files created by TCAE in ../stationnary/postProcessing/interfaceName/0/interfaces.csv. I tried to change the file ./stationnary/system/interfaces. fun by replacing magU by magURel in the list of fields per interface but it did'nt...
