@boerrebj I've run the test models with Dymola and got non-linear system warnings/errors but Dymola manages to complete the simulation. The diagnostics are slightly different when running Dymola 2020 to Dymola 2026x , So I'm including both here in case something rings a bell: |

There was a problem hiding this comment.
I've added a couple of commits for cleanup purposes. After that, there are a couple of things like to discuss before merging:
OpenHPLTest.TorqueEquation: This package contains (I think) meaningless tests. The models themselves are already used by the other base classes and are used in real examples. So I guess we can safely remove that package. So you agree?- EmpiricalTurbine:
- The model contains an unused constant
eps, remove? - The constants alpha and beta have no description and no type so it would be hard to know what they stand for.
- (already fixed) uncecessarily assignment of rho, just use data.rho directly, same with g
- The model contains an unused constant
OpenHPLTest.Empirical:
- I've simplified the Test 04 and 05 models to extend from the sam 01 model like the others. This is when I noticed that 04 and 05 are actually identical. So should vi remove that?
- I've also simplified Test06 and 07 with help of extension.
