What does that "height" variable reference? If it's inside SimMechanics blocks, then that value cannot be changed mid-simulation. It's only if your variable is on a Simulink block (Constant, Gain, etc.) that this will work.
For example,
- If "height" can be fed in using a Simulink Constant block that is connected to a motion-actuated Joint block in SimMechanics, then this approach would work.
- If "height" is a parameter in a Solid or Rigid Transform block, then you will not be able to change these values mid-simulation.
Also, if your model has the possibility for a tunable "height" variable, you still need to pause the simulation, update the diagram, and then resume the simulation for the changes to take effect.
