Coil optimization results in NaN coil parameters #80
Comments
The Problem still persist. Here is another example of a focus run, that starts the optimization but then does not outputs the coils correctly and crashes afterwards: https://datashare.mpcdf.mpg.de/s/dpK1brUJm3qc8zA |
@jimlobsien Thanks for reporting. I will look into this and get it back to you. |
Thank you very much

The Problem appeared a couple of times now. I am using the coil-surface constraints together with the curvature constraint. FOCUS is optimizing which you can see in the nohup.out file, but after the line search fails during an interval update, the coils are written with NaN as parameters. I am clueless what I am doing wrong, since FOCUS actually finds suitable coils.
Please have a look at the files used for optimization: https://datashare.mpcdf.mpg.de/s/vObhcQv4HbHBJci
I am giving FOCUS initial coils and the output was written in nohup.out
Thanks
