Re: Nonlinear Equation Solver
Hi, There's currently no straightforward way of including a Modelica library to Simantics System Dynamics. I think there are two alternatives you can do with that library (or any other Modelica library): 1) You can add the functions in that library by hand to the tool. This basically means that you'...

Re: Modelica and Vensim Functions generated NullPointerExept
This is due to the custom "internal" Modelica solver being set as the default solver, instead of OpenModelica. The internal solver is faster but is missing a lot of features supported by OpenModelica. Switching to OpenModelica solves this issue. The solver can be changed in Window -> Preferences -> ...

Re: Some issues in simulation
Hi,
If the simulation diverges, you'll get NaN. You can also try to change the solver in Model Properties - Method (Euler, Runge-Kutta, etc.).

Re: Some questions on saving the model file and user interfa
Hi Nikhil, Prob.1: Are you sure you saved (=exported) the model instead of saving the simulation results? A model is exported by right-clicking the model in the model browser and selecting Export -> Model. The Disk icon on the toolbar saves simulation results instead. Prob.2: Operating interfaces ar...

Re: Scrollbar
Hi Dhani,
There's currently no scrollbar feature, however the model can be scrolled sideways by holding Mouse3 down and dragging the model or its background.

Re: Problem in Trends
Hi Imran, In your model you have created the predator prey structure inside a Module (ModuleType), instead of the Configuration. The module must be instantiated to be able to simulate it. Attached the model with the ModuleType instantiated. The inside of the module can be viewed by right clicking th...
