- 
                From the Project Browser, select the system to which the solver differential
                    equation is to be added.

                Right-click on a system in the Project Browser and select  from the context menu.
                OR Right-click on a solver differential equation folder in the Project Browser
                    and select Add Solver Differential Equation from the
                    context menu. OR From the Model ribbon, click the arrow
                    next to the Controls tool set name, then select Diff
                        Equations icon. The Add SolverDiff dialog is displayed. 
- 
                Specify a label for the solver differential equation.
                The label can be changed at any time. 
- 
                Specify a variable name for the solver differential equation.
                By default, variables names of entities in MotionView follow a certain convention. For example, all
                    solver differential equation entities have a variable name starting with
                    “diff_”. This is the recommended convention to follow when building models in
                        MotionView since it has many advantages in model
                    editing and model manipulation.

                Click OK to close the window or
                        Apply to continue creating entities. 
                Once a solver differential equation entity has been added to the model,
                    the panel for the equation will automatically be displayed in the panel
                    area.
