The framework DySMo allows users to create variable-structure Modelica models, which can be simulated in OpenModelica and Dymola.

In the case of a pendulum, the two modes correspond to two model structures. In classical Modelica programs, the simulation will fail, the result of simulating this model with DySMo is shown.
The examples have been updated and tested with the following results:
