I tried different options but the error still appears.
I did some tests. I'll tell you more.
I'm using calculation time 7.5.
The drill material is plastic kinematic, the material is SPG sand MOHR_COULUMB.
I wrote above which units I use.
I manage to make the first entry in d3plot, but at the next step an error occurs.
I changed the timestep parameters of the temperature solver and the HC and TC parameters in the MAT_THERMAL_ISOTROPIC settings (for drill and sand).
With these settings, the sand temperature is noticeably very high:
With these settings there are generally negative temperatures
Where to go next? What to watch or configure? Please tell me?
