Detailed Description

Specific physic routine: pulverized coal flame Souce terms have to be precised for a scalar PP on a step of time.

Warning: the treatement of source terms is different ----— from that of ustssc.f

We solve:

$rovsdt D(var) = smbrs$

rovsdt and smbrs already contain eventual user source terms. So they have to be incremented and not erased.

For stability reasons, only positive terms can be added in rovsdt. There is no contraint for smbrs.

In the case of a source term in $ cexp + cimp var $ , it has to be written:

Here are $ rovsdt $ and $ smbrs $ (they contain $\rho volume$ ) smbrs in kg variable/s : i.e.: - for velocity $kg . m . s^{-2}$
