Nalu: a generalized unstructured massively parallel low Mach flow code designed to support a variety of open applications of interest built on the Sierra Toolkit and Trilinos solver Tpetra solver stac...
I am facing unexpected behavior from Nalu. In short, I am rotating a square with a sliding mesh interface at a reasonably low omega (1.5) relative to other cases I...
The user has an ability to specify NOC for the diffusion operator when using the edge-based scheme. However, it looks like this is not fully active for all of the...
In a past graduate class, it was noted that adding data probes with mesh motion was problematic. I believe that this was due to nodes of a data probe being...
For our VOF formulation, and other overset cases, we may want a line-of-site to be used to post-process data. However, running a shock tube case with overset outlined that including...
MomentumMassElemSupAlg was removed. Therefore, a consistent mass matrix can only be run with consolidated - at present. This may have been the intent to deprecate the non-consolidated element approach, however,...
Favre stress on forced reset at a restart is polluted with nans due to a divide by zero: ``` const double rhoAOld = (currentTimeFilter_*rhoAk - rhok*dt)/oldTimeFilter; double uiAOld = (currentTimeFilter_*rhoAk*uiA...
WM-SST does not abstract out the distance to wall (Yp) and, rather, computes this quantity locally. Therefore, the projected approach for utau and saving off of Yp is not used.
The Rodi buoyancy source term has only been implemented for a Ksgs approach. However, for SST, additional source contributions are required. Follow on to: https://github.com/NaluCFD/Nalu/issues/426
A while ago, I changed the timers in Nalu to use wall time, see: https://github.com/spdomin/Nalu/issues/41 However, when running a KNL/threaded/SIMD heat conduction case, I see a discrepancy in the STKPERF...
I have a use case in which I want to specify a velocity inflow from an external data file, however, the simulation precursor is for a non-ksgs model. However, since...
