Dear Sir or Madame,
I am simulating a solid hydrogen storage tank in Comsol. The input for my model is the attached piecewise function defining hydrogen's inlet mass flow. I tried to define it as a piecewise function, but this definition does not recognize the local variables created such as the hydrogen pressure, and orifice surface... How can I properly define this input as it depends on local variables?

Thank you,
Regards.
