Source Term

Hi,

As disscused at the user meeting 2021, there was the question about the source term. In the manual, it's written that it is mm/h if it's distributed but in the software it's written mm/s. What was the final conclusion? It's seems logic that it should be in mm/s.

It there any way to have the history element of the source term it the output (like the discharge)?

Finally, is it right that the following configuration will sink out of the model 40mm/s at each element if this quantity of water is available?

          "SOURCE": [
            {
              "data": -40.0,
              "name": "grille",
              "region_name": "three",
              "sink": "available",
              "type": "distributed"
            }
          ]

Cheers,

Quentin

Re: Source Term

Hi Quentin

The unit of the distributed source is definitely mm/h. The typical application is e.g. input from rainfall.

For your example, let's assume the area of the region "three" is 100 m2. Then 4 m3/h (= 40mm/h * 100m2  = 0.04m/h * 100m2) will be extracted from the region "three", assuming that this amount of water is available.

So far, it is not possible to have to history of the source terms as output for each cell. We will consider implementing this in the future.

Best regards
Matthias
