What is unit of CGUESS and CTOT in PetraSim 2.0?I cannot find them and the examples are too simple and they put the value in directly. Seeking help.

These parameters are described in the TOUGHREACT manual starting on page 31.

 

CGUESS: initial guess for the concentration of the individual primary species (not total concentration), in moles/kg H2O (molal) for species other than H2O and in kg for H2O. Input values of CGUESS do not affect results of speciation calculations, but could affect the number of chemical iterations required during initial speciation computations.

CTOT: if ICON=1, CTOT is total moles of aqueous species, and total amount (in kg) of liquid water for H2O. Molalities are then internally computed as CTOT/CTOT(h2o). If ICON > 1, refer to the discussion of ICON above for the meaning of CTOT.

Thank you very much, I have found the User Guider. I should read more carefully.
