Thank you!

Hello I've been trying to setup ibsEmittance and haissinski codes to find beam parameters with consideration of combined effects of IBS and impedance. I see that it has been done before , but I need some advice. In paper it's said that ibsEmittance code is used to abtain energy spread to use it in H...

Thank you, got confused.

I've created file of particles with coordinates according to n-line search pattern, tracked them and used WATCH file to extract data about survived particles, which gave me X vs dP/P aperture.
In this topic is my detailed request to modify find_aperture function.

Hello Often dynamic aperture in X is larger than in Y. In n-line search mode of find_aperture function we now can choose the step for n-line mode search like step=xmax/n_x. This leeds to fine aperture result for large Y, but poor results for small Y. I propose adding ny for n-line search mode. Typic...

Hello I was trying to run custom ray tracking DX vs DP using MALIGN element and vary_element function. Values fo MALIGN are supposed to be taken from SDDS file. For some reason simulation ends prematurely with message "index 1 has a limit of <= 0". Is it me, or is there a bug with vary_element and t...

Hello,

Is there a GPU version of elegant for Windows? If not, is it going to be? I've seen mention of plans to make gpu vertion for Windows on the forum.

Understood. Thank you for a quick reply.

Thanks! I will try that.

But what about the sum rule of coupled emittances? If we were to use coupling as you discribed sum of coupled emittances won't be equal to uncoupled horizontal emittance from twissOutput for ideal lattice.
