The CV-Simulation Document holds an arbitrary number of CV (cyclic voltammetric) - simulations. The current curves associated with these simulations are displayed in the Client Area of theTab-Window headlined Simulations. The current curve referring to the active simulation (this is the simulation to which the menu commands in the Ribbon Toolbar refer) is plotted in black while the current curves of the inactive simulations are plotted in green by default. The default color settings and some other options for plotting the current curves can be customized in the associated Properties windows.
The concentration profiles simulated for the active simulation are shown in the Tab-Window headlined C-Profiles while the simulated surface concentrations are shown in the Tab-Window headlined Surface Concentrations. The latter also provides the option to display the surface coverage if there is at least one redox couple comprising adsorbed species.
The menu commands available when activating the Tab-Window: Experiments enable the user to import experimental data files and to prepare the imported files (if necessary) before using them in a Data Fitting Project. The fitting procedure can be started in the Tab-Window: Data Fitting. The fitting procedure is based on a non-linear regression strategy aimed at minimizing the overall standard deviation between simulated and experimental CVs by modifying the thermodynamic and kinetic parameters of a user-defined mechanism in an iterative way. As long as the fitting procedure is running, a comparison between the currently simulated CV and its experimental counterpart is shown in the Tab-Window: Data Fitting. If the fitting procedure has terminated the user may want to see how well the simulated CVs agree with the experimental ones. All selected couples (experimental CVs and their simulated counterparts) are shown in the Tabbed Window: Compare Curves. The user may also want to know how the overall standard deviation between simulation and experiment is affected when varying one particular parameter. This information can be computed and displayed in graphical form in the Tabbed Window: Chi²-Tests.
The Tab-Window: Plot Graph can be used for plotting data (x,y-couples) in graphical form. The x-y-couples can be either directly entered using the editor provided for this Tab-Window or imported from the screen info shown on other Tab-Windows after applying the Plot Graph command. The screen info is obtained either by means of the Min/Max Info command or by retrieving the screen coordinates of individual points by double clicking on the a particular current point of the active curve (see video Getting Started for more details).
