Start with CL, central volume only, fix the rest to zero, at least to define the range of parameter values. You may add more later if needed. 2. This is an error: W = SQRT(THETA(8)**2+THETA(9)**2*F*F) you should use W = SQRT(THETA(8)**2+THETA(9)**2/F/F) 3. This is an error as well: DADT(1) = - K12*A(1) - A(1)*VM/(KM+C1) DADT(2) = K12*A(1) - K21*A(2) + K32*A(3) - K23*A(2) you are missing K21*A(2) in DADT(1) = - K12*A(1) - A(1)*VM/(KM+C1)+ K21*A(2) Leonid
