Re: unit conversion
 
This can be be done, but in addition to time itself, you must scale all other input variables whose units contain sec by the factor 1000, as appropriate. For example, the kinematic viscosity ENUL is by default in m^2/s, and so if we define TSCALE=1000., you must divide ENUL by TSCALE, so that ENUL is in units of m^2/ms.
