Hi
Just wondering if there is a way to increase the threshold of "zero mass".
This is because I have a lot of simulation runtime with masses as low as 1e-30 it's not considered "zero" because for fortran real*8 is below 1e-38 (with option -funsafe-math-optimizations in gfortan otherwise the threshold is as low as 1e-45).
In the code it seems particles are only deleted when rmass <0.0, i.e. a hard zero.
If no hysplit option, what Fortran compilation flags do you recommend for intel compiler?
Thanks in advance
Cheers

Re: Almost zero mass
You can use the
FRMR
namelist variable.

FRMR=0.01
would remove particles that had mass less than 0.01*total_mass.
