    initial v1  
    1 Could you please elaborate on what isn't working correctly? max/min does not generate events, so noEvent has no effect in your example and is optimized away by the compiler. The only issues I can see are modelling related, i.e. you have the equation system
    2 {{{
    3 Smax = max(Smax, s)
    4 flange_a.s = s
    5 flange_b.s = Smax
    6 }}}
    7 which can't be solved since there are four variables involved but only three equations. Likewise you get the equation system
    8 {{{
    9 flange_a.f = 0.0  // Automatically generated since flange_a.f is an unconnected flow variable.
    10 flange_a.f = 0.0  // Added by you.
    11 }}}
    12 So the equation system generated by the model is simply unsolvable. To make it possible to simulate the model you'd need to remove the flange_a.f equation and add another equation to the first equation system.

     3Edit: Removed wrong analysis, I didn't realise that the test model was just supposed to be part of testcase.
