Description
In the following model the function f1 is simplified wrong to 1.
For some reasons the function f is constant, when f1 is simplified.
function f input Real x; output Real y; output Real y1; algorithm y := exp(x); end f; function f1 input Real x; output Real y; algorithm y := 1 / f(x); // don't work //y := (-f(x)) / (-2); // works //y := f(x) / 2; // don't work //y := f(x) + f(x); // don't work !!! end f1; model A Real y; equation y = f1(time); end A;

I think these probably just lack the DAE.TSUB on the right side. Factors, etc, should not handle tuples!

Postponed until 1.9.1

This ticket was not closed for 1.9.1, which has now been released. It was batch modified for milestone 1.9.2 (but maybe an empty milestone was more appropriate; feel free to change it).

- Resolution set to worksforme
- Status changed from new to closed
Works as expected in v1.13.0-dev-155-g68350e9
Okay, I found a missing case for tuples in ExpressionSimplify(r16348). So that the first 3 cases are fixed.
But following is still open:
I guess we need to expand tuples somewhere.
