maki Posted July 24, 2013 Share Posted July 24, 2013 Hi I have been trying to calculate microbial kinetics using custom rate law (script and script file). According to the support’s advice, I started to try it under simpler setting. I assumed that two kinds of aerobe utilized different electron donors. Kinetics settings were the same for paying attention to apply custom rate law of Aerobe-2. Custom rate law in script or script file was set based on the support’s advice as below. I also assumed that when ‘Acetate’ used by Aerobe-1 become below 0.0001, Aerobe-2 start the reaction. The bas file was converted to text file and attached. IF molality ("Acetate") < 0.0001 THEN 20 ELSE 40 20: rate = rate_con * biomass * FD * FA * TPF GOTO 60 40: rate = 0 60: RETURN rate In spite of various trials, the calculations stopped just before reaching 0.0001 in the concentration of 'Acetate' and never converged in all cases. How should I handle this problem concerning the custom rate law? In addition, when the React program with custom rate law in ‘script’ editor of the Reactants pane is closed, and opened again, equations of ‘script’ showed the irregular description and brought an error. Could you check the problem, too? Best regards, Maki Custom_rate_law_trial2.rea Acetate.txt Quote Link to comment Share on other sites More sharing options...
