Hello,
I'm new to modelica programming and modelling, so forgive me if  this question is somehow stupid. I need to change the mass value of a "point mass" block (multibody), when a certain boolean condition is met. I wrote the code but the system tells me that the mass value of a point mass is a parameter, and so I cannot change it during simulation.  Is there any other way of doing so or I'm trying to do something that's simply not possible?
