Choose the correct answer.

One of the most common reasons to utilize a SysML-Modelica integration is to solve and analyze system dynamics models. Modelica is a language for modeling complex physical systems based on equations and components. SysML is a language for modeling complex systems based on diagrams and textual notations. By integrating SysML and Modelica, system dynamics models can be defined in SysML using parametric diagrams and constraint blocks, and then solved and analyzed using Modelica tools and solvers.
