what's wrong with simulation of transport line orbit correct

Post by shancai » 23 Oct 2009, 03:33

hello,

The reference orbit have a change and is not zero.
I don't know what's the reason.

Thank a lot!

Shancai,

I ran your simulation but get a different result, which is attached here.

Can you tell me which version of elegant you are using? The one-to-one trajectory correction was updated in the last release, so it might make a difference.

Shancai,

I don't see any obvious problems in the log file. Can you make a tar file of all the output files and post it?

Also, what operating system? 32 or 64 bit?

Thanks--Michael

Shancai,

I can confirm that there is a problem with your simulation for recent versions of elegant. The reason is that you are using CSBEND elements with the default integration parameters. These defaults are not good for most cases (this changes in the next release).

Try setting N_KICKS=12,INTEGRATION_ORDER=4 on all the CSBEND elements. It should fix the problem.
