 <p>You can override various internal model calculation routines with custom python code using the <b>Script Manager</b>. As of <b>DWSIM v5.6 Update 12</b>, you can override calculation routines from Unit Operations on the flowsheet, Fugacity, Enthalpy and Entropy calculation routines from Property Packages added to the flowsheet and use custom Flash calculation routines through User-Defined Flash Algorithm instances added to the flowsheet.
 </p><p>The custom functions must be defined and set only once before working with your simulation. For this reason it is better to associate your code with the <b>Simulation Opened</b> event after it is ready for production, so it can be automatically executed on every simulation file opening/loading.
 </p><p>If you choose to make any modifications to the code, don't forget to update it by running the script using the 'Run Script' button on the Script Manager.
