Diodes not working

[Pavol Privitzer]

There is an unexpected sinus wave on the diode's i variable in the attached simple model.
Maybe the model is somehow incorrect (because of me), but there should be a filtered half waved sinus instead.

If you give me a hint to solve this, I'd be happy,
because it's a big blocker to our modeling ...
... the same problem we have with other models with valves (our physiological models).

I can try to fix this myself, but I will need a hint with the generated
code for diodes, specially I would like to understand the mini linear equation system,
a link with a theory about it would be helpful.

Best regards

PS: there is not yet created a version 1.4.4. (my actual version) in the version combobox when submitting the bug

Actually this is the model, I'd like to work.

Well, I've found, after I tried my posted model DiodeTest.mo in MathModelica Designer and dicovered myself to try to stop the force of sineCurrent source on the diode (I am better modeller in physiology ...), so the TestDiode.mo is not the model I'd like to work.

But, after I changed it to sineVoltage source it worked well in the MM Designer, but unfortunately not in OpenModelica, where it showed just a strange step function.

Please, look at the second attached model DiodeTestVoltSource.mo.

Strange, I have a model of a full wave rectifier using four ideal diods from MSL (see attachment) which works fine, I will try to look into it next week.

Model including diods that work.
