Thank you very much for replying! The simulation run with the parameters shown in this file though. But, I'm not sure what exactly IDDESdelta does or what is the equation of this filter? Since I'Il need to justify the parameters/filters for a paper eventually, I try to find some documentation on openfoam website and there is not much of it. Do I need to take a look at the code at this point? Plus, because I use the
DEShybrid
div scheme for the moment, I guessed that it was needed to specify the parameter
hmax
under
IDDESDeltaCoeffs
(didn't find documentation that these two are related though, but I noticed in some tutorials that when
hmax
is use in
DEShybrid
,
hmax
is specify in
IDDESDeltaCoeffs
). About the
smooth
section, I've seen somewhere that its use to help having better results for the cells close to the region where two different levels in the mesh coexist. I would certainly appreciate if someone could confirm that. About the different filter, it would be nice to have something similar to this for each one: https://caefn.com/openfoam/filter-width-maxdeltaxyz
