This ones work with `eddyNekNek` on Summit Use temporary session file and put two meshes under separate folder. NVME is not used so we don't need to set OCCA_CACHE_DIR here,...

**Describe the bug** With empty `UDF_ExecuteStep`, the `*0.f0*` files generated by NekRS using `writeControl` will have timesteps=0 in the header. Paraview will have issues when there are multiple files with...

When building the multigrid levels, I saw some negative jacobian. ``` Nq: 8 cubNq: 11 J in range [2.15238e-06,0.204362] and max Skew = 292.403 ... =============BUILDING MULTIGRID LEVEL OF DEGREE...

Current mesh metrics are printed after userdat2, which might not be the mesh used in the simulation. We might also want to call mesh_metrics (needs xm1 to xc first) after...

Hi, Is it possible to split the hip compiler from the wrapper? The current hip build seems to only support clang. https://github.com/LLNL/blt/blob/29eecef7652728ec37d9fe0b7d7f41e3184ac7eb/cmake/thirdparty/BLTSetupHIP.cmake#L83-L87 I'm trying to compile Ascent on Frontier using...

This is a working in progress draft PR preparing for the next release. Original code is from Victor Mateevitsi (@mvictoras) ## Feature Enable on-the-fly visualization directly rendered on device without...

### Support Newton cooling BC (Robin) for scalars. In the examples/robin, we have three tests. 1. TEMPERATURE: diffusion equation with Newton cooling BC. The temperature decays at a known asymptotic...

**Describe the bug** It appears that we don't pass the "AMGX CONFIG FILE" to solver->options so it's not using the user specified "amgx.json". **To Reproduce** In par file ``` [PRESSURE]...

**Describe the bug** We should only call `bcMap::checkBoundaryAlignment` with v-mesh. https://github.com/Nek5000/nekRS/blob/4f87e0e2ec0492e2a3edf27791252d6886814d00/src/setup/setup.cpp#L253-L262 **To Reproduce** This bug can be observed in the conj_ht example with the following changes where the number of...

This is a minor issue that won't change the result unless the overflow number get exact 0, nchange = 2^32 for example. In distf (and also in cheap_dist?), we loop...
