Potentials – Adding Plotting of Output Data
This morning, I was able to finish up the plotting of the output data in Potentials. It's not generating the right numbers, but the NSView Quartz 2D drawing is working, and the linear color interpolation is doing its job as well. What seems to be the problem is the cLAPACK call to solve the system.
I know this was all working years ago, so it has to be in the cLAPACK code in the Accelerate Framework in macOS - and there, anything is possible. Could be the format of the banded matrix storage changed, or the format of the numbers or structure of the A or b in the equation... but it's something... because I looked at the output, and the numbers just are not right.
The blank area at the bottom is where the data was either NaN or -Inf, and I know that's not right. And then the potential field distribution is all wrong. No way this is right. So I'll come up with a simpler test case, two line conductors, and a smaller grid, and see what's happening in more detail. It shouldn't be too hard to see what's up.
Then, it's just a matter of seeing what's next. Things are taking shape! 🙂
