Reduce plot resolution to win time

[ptc-4343971]

I want to plot an integral with one of the boundaries on the x-axis. The problem is, it takes several minutes.

Can I set a lower resolution of the plot to speed it up?

Please show mathcad worksheet.

It is calculating the required length of a sheet pile wall.

The problem is the last plot.

Perfect, thanks!

Very interesting ways of calculating the required pile length. I tend to do it a little different.

Do you follow a specific method?

Mostly I follow a handbook by Göran Sällfors which I think follow Eurocode 7. The assumtion that the wall will rotate around 0.8*(wall length below bottom of excavation) is from another swedish handook thas is widely used. Of course they dont use integrals in the handbooks, that was my idea.

Which part do you do different?
