Hi Michael,

I just downloaded the latest version of elegant, and now the bug is gone. Thanks for your kind help!

Hi Michael, It appears that setting expand_hamiltonian to 1 of a CSBEND produces incorrect result during tracking, for the latest 2019.2.1 version. In the attached example, we compared the results of tracking a particle through a CSBEND w/ expand_hamiltonian set to 1 and 0 (default value), a nontriv...

Hi Michael,

I just tried the newest version of elegant, this problem was gone. Thank you for your kind help~

Dear Michael and all, I included in a ring lattice two BMXYZ elements each with a 3-D field map, and wanted to study the effect of these field maps on the closed orbit, emittance, etc. One thing I couldn't understand now is that the second BMXYZ element seems to have no effect on the closed orbit. I...

Hi Michael, In the attached example, I tried to add an ETILT error of 0.01 rad to a CSBEND, and a TILT error to a KQUAD. I assume elegant follows the same local reference coordinate system as in MAD. Then tracking results seem to indicate a positive ETILT rotates a CSBEND in the counter-clockwise di...

Hi Soliday, Thank you for your prompt reply! I have set "export DYLD_LIBRARY_PATH=/opt/X11/lib/flat_namespace" by default, and this worked for macOS 10.13 before I upgraded to macOS 10.14. Anyway, I can still export the sddsplot results to png files, just a little bit inconvenient. Best, Zhe

Hi, I've upgraded my MacBook to the latest macOS 10.14, but I could no longer run sddsplot properly. For example, when I run "sddsplot -col=s,betax Basic.twi", I got an warning of "Warning: XmManager ClassInitialize: XmeTraitSet failed", followed by the following Error info: Error: attempt to add no...

Dear Mina and Michael,

We did use CST to obtain the impedance and used Pelegant to do the tracking w/ impedance. I had a short note regarding the sign conventions, as shown in the attached files. I hope this helps.

Best,

The problem is solved now, thank you!

Hi, I'm facing an annoying problem with sddsplot. I built SDDS 3.5.1 and ELEGANT 33.1.1 from source on a RHEL 6.5 server, everything works perfectly except when I want to save a plot using the png device. To be more specific, when I run the following command sddsplot -col=s,betax twiss.twi -device=p...
