[FLASH-USERS] value of Ye for single species runs

[Slavin, Jonathan]

​Hi Ernesto,

I don't specify the runtime parameter addThermalFlux.  Instead I set
diff_useEleCond, useConductivity, useDiffuse, and useDiffuseTherm to .true.
and specify
​REQUIRES physics/materialProperties/Conductivity/ConductivityMain/PowerLaw
REQUESTS physics/Diffuse/DiffuseMain/Unsplit
​Should I change one of those?​

​I note that in the log file that
hy_fluxrespresentation = fluxes
I'm not sure exactly what that means.  My goal here is to verfy that
​thermal conduction is operating as I expect by comparing evaporation of a
spherical cloud in 2D cylindrical symmetry with analytical results derived
for steady flow including saturation of thermal conduction (Dalton & Balbus
1993).

Regards,
Jon
