USER DEFINED SCALARS

yann

hi,

i would want to know how to defined user scalar for which transport equation may be solved or not, by the way of pil command.

for instance if i want to define the mach number as u/sqrt(gamma*r*T) , so i dont want to define a transport equation for it, how can i define that user scalar as a function of solved and existing flow variables...

thanks

in addition i saw in some Q1 that there exist some variable that phoenics recognize such as MACH PTOT (total pressure) but i cannnot find any list of such variables in POLIS or whatever... where can i find the complete list??
