CircleInhom - actual status?

[MattBrst]

In the code I find quite a bit of code for the circular inhomogeneity. However, I did not find any examples so far.

Could you inform us about the actual status of the circular inhomogeneity?

The circular inhom theoretically works I believe, but isn't currently operational since the class design/methods do not follow the new TimML design. So you might get it to work by itself, but not in combination with other TimML elements.

The circular inhomogeneities have been implemented and work(ed) well, but they have some limitations, which is the reason that they are not very accessible or that there are no examples.

The two most important limitations are:

1. Computation becomes difficult when the radius of the cylinder is large compared to the leakage factor. This can be overcome by implementing asymptotic expansions for large arguments.
2. They cannot intersect polygonal inhomogeneities or area-sinks.

What use case did you have in mind?

I wanted to model a sand column (dutch: 'grindpaal') from an upper to a lower aquifer through a confining layer.

Inspired by the circular building pit notebook I am trying a PolygonInhom as approximation for the (circular) sand column and that seems to work out well.

Just make sure it doesn't intersect a polygonal inhomogeneity. And be careful if you have defined areal recharge in some fashion. Not sure how that interacts with the current version.

EDIT: Since I did not get the CircleInhom working, I switched to a polygon inhomogeneity. And then I encountered the following:

I tried the polygon inhomogeneity in combination with a CircAreaSink, but then I get an error message that CircAreaSinks cannot intersect with inhomogeneities.

Now I use HeadLineSinkStrings to generate a flow pattern and that seems to work well in combination with a polygon inhomogeneity.

As stated below, the CircAreaSink works fine

Sorry, I was referring to the CircleInhom class, which isn't up to date with the latest TimML method names. CircAreaSink is up to date and should work.
