Logging discharge of SOURCE.EXTERNAL_SOURCE

Sometimes I'm using SOURCE.EXTERNAL_SOURCE with negative discharge.  I think
currently it is not possible to directly log the actual amount diminishing. I
know, I could circumvent this by balancing logged stringdefs above and underneath.

So this is a feature request for logging SOURCE.EXTERNAL_SOURCE directly.

Thanks and greetings,
Michel

Re: Logging discharge of SOURCE.EXTERNAL_SOURCE

Hello Michel,

it should be possible to log the external source discharges since Basement version 2.4. With the  special-output type 'element_history' the added or removed discharges  (sources or sinks) are written to file for each specified element. For example:

            SPECIAL_OUTPUT {
                output_time_step = 10
                type             = element_history
                element_values   = (external_source_discharge)
                element_ids      = (496 294 170 36 509 605 674 726) // all elements of to the EXTERNAL_SOURCE
            }

I think this output should also work for sinks (= negative sources). However, you still have to sum up all the element values at the end.

Regards,
Christian
