Hello,
I’m new in mfix-exa. The case I’m working with it’s already running in mfix, but it takes too much time, so I’m trying exa. Now I’m facing the error:
amrex::Abort::0::CUDA error 700 in file /home/stagiaire/mfix-exa/subprojects/amrex/Src/Base/AMReX_GpuDevice.cpp line 756: an illegal memory access was encountered !!!
I don’t know if anyone can help me? Here is the file:
pts_m_flip.stl (20.7 KB)
MiXER.inputs.txt (7.3 KB)
I don’t know what MFIX-Exa version you are using, but
use_stl
is not an MFIX keyword, and you have both
mfix.geometry = stl
mfix.geom_type = stl
The latter (geom_type) is not a valid key.
These are not the cause of your error, but you might want to clean this up. Loading in the MFIX-Exa GUI will catch these errors, as will setting
mfix.stop_for_unused_inputs = true
For what it’s worth here’s a preview of the geometry/regions:
There may be an issue with the definition of the outflow region (?)
It’s not shown in the preview, and the inputs file has:
regions.outflow.shape = Box
regions.outflow.box.lo = 0.1545 0.0815 0.3020
regions.outflow.box.hi = 0.1815 0.1035 0.3020
Note that you have specified Box but the zmin and zmax coordinates are equal.
Hello again,
I changed the figure to .csg and see if that works. So first I tried to fix the fluid flow before introducing solids, however when I run the case it seems that there is no flow into the figure. What can I do?
