Hey guys,

I´m modelling a thermal system with Simscape in which the thermal mass of one of the components is changing after it reaches a certain amount of temperature (the material starts to burn). Because of that I need to change the mass parameter in the "Thermal Mass" block after a trigger temperature is reached.

My Problems are:

I can´t define an array for the mass parameter. I would also accept that the loss of mass is like a step function (changing form 500g to 250g), if it´s not possile to define an array to describe it.
I can´t connect the "Thermal Mass" block to a Simulink trigger signal, after which the loss of mass appears.

I would be very grateful, if anyone of you could help me out with these problems.

Best Regards

Cem
