@madelestin Unfortunately, in the current released version, you can only check this by outputting the simulation results and examining whether any instabilities occur. Typically, extreme stresses or particle overlap can cause the soil domain to explode, leading to excessive memory usage and termination of the simulation. Adjusting the particle spacing can sometimes help avoid instability points or stress concentrations and reduce overall memory usage.

I have quite the same issue, the simulation stop midway is there any way to check what the cause of it? because as i changed the particle distance the error is no longer that
but i would like to know the effect of particle distance to my simulation

Hi @brayan-ruiz. That error only means the simulation hasn't run, and there is no output to display. Please download and try sample projects to see if it works.

I'm having trouble running the program. When running the simulation, the program displays the following warning.

16:25:47 Traceback (most recent call last):
16:25:47 File "", line 77, in on_sph_sim_finished
16:25:47 FileNotFoundError: No such file or directory: 'C:/Users/ASUS/Downloads/GranularFlow2D/GranularFlow2D/GranularFlow2D_out/Run.out'

I have tried installing previous versions of FreeCAD, and installing without my antivirus activated, and I have not been able to solve the problem.
