Hello Everyone

I am working on a wastewater pond modelling for almost a year. I am really enjoying working with D-waq. Besides my results seems very well. I should thank you for your excellent software and support team. However recently I have a difficult with CO2 reaetation . since I activated this process my model does not run and the error bellow appears in the window.


runid: 18nov

Parallel processing with 1 processor(s)

SIMULATION STARTED

INTEGRATION ROUTINE = 15
Illegal option for reaeration formula
Stopped with error code : 1

I attached lsp and inp file. If anyone can help me I would appreciate it.

Thanks

Hello Fatemeh,

the documentation states that for CO2 only the options 0, 1, 4, 11 and 13 are available. Would one of these suit your purpose?

Dear Arjen

Thanks for quick respond and, I know what is the problem now. I did not pay attention to SWRearCO2 options. I think one of them can be the one I want.

Dear Arjen

I changed SWRearCO2 to 0, 1, 4, 11 and 13 but I have the same problem. Did I miss something else?

Are you sure that you changed the right parameter? I checked the code and also ran a small test - this message only appears if the option is outside the range 0 to 13. The options 11 and 13 are specific to CO2 but the others can be used - with some caution perhaps, as they are based on the physics, not the chemistry - for CO2 as well.
