4450	Most PhotoVoltaics examples are not working any more	Christian Kral <dr.christian.kral@…>	Patrick Täuber	"As of the latest version of OpenModelica I noticed, that most examples do not simulate any more. I made a snapshot of http://libraries.openmodelica.org/branches/overview.html and attached it to this mail. My actual OM version is

{{{
OMEdit 1.12.0~dev-318-g47cd820
Connected to OpenModelica 1.12.0~dev-825-g7fd8f31
}}}

So apparently none of the models of PhotoVoltaics_TGM simulate so far, and only three models of PhotoVoltaics simulate right now. In the versions 1.9 and 1.11 there worked a couple more models than today. 

In practically all simulation experiments I get a similar error message:
{{{
stdout | error | <p>Simulation process failed. Exited with code 255.</p>
assert | debug | <p>division by zero at time 0, (a=0.6388888888888888) / (b=0), where divisor b expression is: plant.diode.Vt * plant.diode.m</p>
}}} 

To me this error message sounds like an initialization problem, as neither plant.diode.Vt nor plant.diode.m are zero. So this might be related with an iteration problem.

However, I were very unhappy if you would release version 1.12 of OpenModelica without having proper support of the PhotoVoltaics library, especially, as the PhotoVoltaics libraries were supported a lot better by OpenModelica already.
