Ding, You can use the divide_elements command to subdivide the drift spaces. For example ÷_elements name = *, type=DRIF, divisions = 10 &end This command needs to go before run_setup. The manual page is here: http://www.aps.anl.gov/Accelerator_Systems_Division/Operations_Analysis/manuals/elega...

I forgot to say, you can also have digits 0-9 in the name.

Michele, The rules for naming elements and beamlines are as follows: * The name should start with an alphabetic character (i.e., a-zA-Z). * The name may contain any of the following characters: a-z A-Z ~ @ $ % ^ & - _ + = { } [ ] \ | / ? < > . : * The name should no contain any of the following char...

Ping,

Thanks for posting the example.

I recommend using the attach lattice file instead of the one you posted. It has synchrotron radiation (classical only, no ISR) enabled, which gives more reliable determination of the momentum aperture.

Weiming,

Thanks for posting this. I'm planning to include a built-in kick-map element in elegant in the next release.

Also, it should be possible to have elegant compute the matrix for the SCRIPT element using tracking, as it does with CWIGGLER.

Weiming,

I have confirmed this bug. Thanks for bringing it to my attention. It will be fixed in the next release.

For those who can't wait and who build from source, a modified version of the relevant file is attached.

Vadim Sajaev reported a bug in elegantRingAnalysis when it is run without the Grid Engine queue. Postprocessing would fail when attempting to merge the log files.

The problem was in the file elegant.tcl, which goes in /usr/local/oag/apps/lib/$HOST_ARCH/. A corrected file is attached.

Here's how to make an animated GIF movie from data from elegant. You'll need the ImageMagick programs in order to do this. Imagine that you are tracking many turns and want to make a movie of the particle distribution turn-by-turn. In the .lte file, you need a watch point set up to record particle c...

I used Pelegant on one of our computer clusters at APS to perform a simulation for ~100 turns (actually only 93 as I inadvertently stopped the job). This took several days on 32 processors (I didn't keep track of exactly how long it ran.) The results are pretty interesting, as the attached animated ...

Sorry, I didn't read your entire message.

Can you look in /usr/local/oag/apps/lib/linux-x86 and see if there is a file APSDebugPath.tcl? If not, try reinstalling the OAGTclTk rpm.
