fTetWild seems to produce non-deterministic results

[OveSo]

Hi there,
I'm happy to have another option like fTetWild, with which you can generate a TET mesh from an STL hull mesh.
However, it seems that the same input data produces different result data - at least in a different order.
Could it be that pointer-based sorting is used somewhere in the code?
Kind regards,
OveSo

I also found out that by using the --csg option, you end up with a different mesh (i.e., different number of elements and nodes) with every call. I found that there is a random generator used in some places, however, it is actually seeded with a constant seed, thus I'm not sure why this randomness exists?
See

fTetWild/src/Mesh.hpp

Lines 32 to 38 in 5bd0135

	static int next(int min, int max)
	{
	static std::mt19937 gen(42);
	int res = (gen()-std::mt19937::min())/double(std::mt19937::max()-std::mt19937::min())*(max-min)+min;
	return res;
	}

It would be really nice to have deterministic results - is there any hint how to achieve that?
