Installation:
Hello, I’ve tried to run the Tutorials and all the tutorials I tried with STL involved crashed with the error:
FATAL Error: There are no standard fluid cells in the computation.
Please verify geometry and mesh settings.
If using an STL file to define the geometry, this may be due to
normal vectors pointing in the wrong direction.
Even 3.1. First tutorial — MFiX 23.3 documentation, that is a complete case that only needs to run, crash with the same error.
The tutorials: 3.2. Two-dimensional fluidized bed, Two-fluid Model (TFM) — MFiX 23.3 documentation, and 3.3. Two-dimensional fluidized bed, Discrete Element Model (DEM) — MFiX 23.3 documentation can be run without problems, but
3.4. Three-dimensional single phase flow over a sphere — MFiX 23.3 documentation in which there is a sphere made of a STL, crashes again.
I’ve checked the normals, and they are correct. I do not know if there is something I’m doing wrong, or there is some libraries that are not installed in my linux box.
Please, let me know if there is something I’m missing, or there is an error related to STL files.
By the way, I’ve installed mfix 23.2, and I have the same problems.
