Criteria for successful runs.

[365andreas]

I am Andreas Triantafyllos from Huawei and I would like to ask for some clarification about the evaluation of a simulation.

I was wondering if there are specific references that explain the criteria to consider a simulation run as successful.

In particular, I am referring to:

miniMD/ref/run_one_test

Lines 131 to 132 in 7576016

	x=sqrt(2)*(0.5+atan2($1-d*'"${precision}"',50)/3.1415);\
	v=sqrt($2*$2); if(v>stddev_t*x+add_t) t=t+1;\

How was the formula that takes into account the precision of floating-point numbers derived?

and

miniMD/ref/run_one_test

Line 138 in 7576016

if(t+e+p>3*0.38*total) print " Failed (" t/total " ; " e/total " ; " p/total " ; Expected 0.32+-0.06)";}' out.compare

Why do total errors compared to the reference output have to be in the range 32% ± 6% in order to consider a run as successful? How was this range chosen?

I would be grateful if anyone could share any explanation or reference to the literature about the above.
