Hi,

OpenModelica comes with WasteWater 2.1.0, why do you need an older version?


Cheers,

I meant 2.1.0.  Both OM 190 and 192 are not loading it. I am on Windows 7 64 bit

You can try with the latest nightly build:
https://build.openmodelica.org/omc/buil … ly-builds/
it seems to work fine to load the library.

Thanks Adrian,

I tried to load Wastewater 2.1.0 on OpenModelica 1.9.3, Windows 7  64bit.  It still failed to open it.  I see the following error message:

[1] 10:41:13 Syntax Warning

I think, the problem may be from the WasteWater package. Because, I run another model on OM 1.9.3 and it did work without problem.

However, I noticed the the omc of 193 does not keep the parenthesis '() within mathematical operations.  Why?  Because, this might be risky to get the right output.  The parenthesis give more control to aretemetic operations order.

Hi atame,
we have the Wastewater library running since a few weeks. Getting it to run in the first place was admins' job. From what I understood the library loaded just fine but they had to set start values for concentrations (in example plants) to be unequal to zero in order to avoid division by zero.

I than noticed that saving a modified library was not possible in the original format so I save it in a WasteWater.om file.
