Create option to specify the control point of a head-specified well #38

Open mbakker7 opened 4 years ago

mbakker7 commented 4 years ago

The control point of a head-specified well is at the right side of the well on the radius. Sometimes it is useful to have the control point somewhere totally different, for example on the edge of a building pit.

Somewhat related, we once discussed an element consisting of a series of wells designed to obtain a certain drawdown at a point. I'm not sure whether this was possible or there is the issue of infinite possible solutions, but something along those lines would be cool to have?

Yes, that is related. The thing is that right now we need the same number of equations and unknowns. It sounds like you suggest multiple wells and one point where the head is specified. To solve for the discharges of the wells, you need to specify something extra like that they are all the same (but unknown). Is that what you had in mind?

Yea, the idea came from the way vacuum dewatering is implemented, with several wells attached to the same vacuum pump (as far as I know anyway). So multiple wells with equal discharge with a specified head a at a point would work.

That's actually pretty easy, but a separate issue. It is similar to a LineSinkDitchString. Can you create an issue? And if you are bored sitting at home, you may even want to take a crack at it!
