Hello list,

I am wondering why this is not working correctly. If I use

variable V equal vol

variable Rho equal ${totMass}/$V*1.0e24

fix 2 all ave/time 2 5 10 v_Rho ave window 10 &

file time-avg.dat &

title1 "# Step rho(g/cm^3)"

Then Rho is not updated; I get the same value at all time steps.

If I use

variable Rho equal ${totMass}/vol*1.0e24

I get the correct updated result at each time step. Why isn't V updated

at each time step?

Thanks,
