About inlet Phase fraction:
I don’t know how to implement inlet phase fraction at the liquid inlet in simscale. Essentially, this can be done by applying bounding box in ‘setFieldsDict’ file in system folder of openfoam, as per the conventional way. I asked roy_g for input, as well as I would also like to hear from you about it.
About time step:
Yes, I kept adjustable time step along with Courant number of 0.5, but I was gonna start with 1E-5 just for the safer side.
About sharp edges:
I already changed the geometry and added the curvature on the corner for better boundary layer and reduce the turbulence. but further changes in geometry will defy the actual purpose of the geometry. Hence, I won’t be able to do that.
About 32 cores:
The first run that I did, it actually ran perfectly for 1 time step, until I saw Courant number at 256.000001, and after that it diverged. And I received detailed event log and solver log, I even learned from solver log that its running with ‘LTSinterFoam -parallel’. But later all ‘runs’ I only received ‘An error occurred’ and no detailed logs. So that’s the scenario where I wasn’t able to figure out what’s wrong with case, since all settings and pre-processing was showing ‘green tickmarks’.
Apart from that, I have another project in which this geometry is bigger with even more complex corrugation patterns. I ran that case on 16 cores with 5.2M cells for 11 time steps.
I apologies for that, but I’m stuck in scenario where professor suddenly preponed the deadline while no results in hand. and no information for debugging apart from one single line message saying “an error occurred”
