Add generic network example

[marcusfuchs]

This adds the 25-building generic Aachen network. It may be necessary to also add a few component models.

[marcusfuchs]

I added the Aachen Use Case to Annex60.Experimental.Pipe.Examples.UseCaseAachen.AachenGeneric on the pipe_issue69_AachenUseCase branch.

@bramvdh91 @GersHub Could you have a look at this network and tell me if there is something we should change about the model?

On a side note: I get a lot of errors when loading the current version of bramvdh91/issue264_pipe in Dymola:

@marcusfuchs @GersHub Sorry for all the errors, I pulled the master branch of the original repository, apparently not all issues were solved yet... I will look into this now! Thanks for committing the network!

Edit: I don't get any similar errors, but the validation models don't compile in my local version either. I'll let you know when I've solved this

@marcusfuchs @GersHub The example looks really good! It's running now, although translating (?) takes ages, it seems. The simulation finishes around 13s on my laptop.

Still a lot of non-linear systems, in other words :)

I've quickly tested what happens if I split the current pipe volume into an inlet and outlet part, resulting in the following statistics:

I have changed all pipes and connections in the example to vectorized equivalents (on the branch for issue #20), see 788ef781c70c955b35244911b6a759fe7e8cf19a. All numeric jacobians are avoided, as well as non-linear systems. On my machine, the case runs in under 2 seconds. However, checking and translating takes about 1:40 min.

[bramvdh91]

@marcusfuchs @GersHub I've done a quick test with MSL pipes to check the checking/translation and compilation time, and I end up around the same time. I had to assume 20 elements per pipe (which is on average a good estimation) because Dymola will not accept a variable number of elements (I used ceiling(length) for the number of elements, with no success).

[bramvdh91]

@GersHub I just pushed the MSL version to the pipe_issue69_AachenUseCase branch.

[bramvdh91]

I think this can be closed after merging.
