Hello Michael,
Unfortunately, it does not work when I am trying other parameters.
Is there an alternative to calculate the periodic solution?
Thanks.
Regards
Wei Hou

Beamline is unstable when matched=1 is set in twiss_output
Hello, I am using Elegant to optimize FODO lattice parameters for given drift, quad's lengths and phase advance. However, I run into some problems where Elegant cannot find the periodic solution of my FODO lattice. For example, this set of parameter works fine. elegant elegant.ele -macro=driftlength...

How does Elegant use input file for FTRFMODE?
Hello Michael, How does Elegant use Shunt Impedance, frequency and Q-factor to calculate the voltage and phasor? Here's how I prepare the data. I have a spreadsheet of data containing kick factor, frequency and Q-factor. Screenshot from 2023-10-09 10-36-11.png I calculate Shunt Impedance based on fo...

Energy of different bunches in multi-bunch simulations
Hello, I have a question regarding the multi-bunch simulation. I ran the simulation with 100 bunches, and use WATCH element to keep track on all distributions. I also used MALIGN with different PID to offset each bunch with different offset. I found that the beam energy of all bunches are the same, ...

Re: Problems on running Pelegant with FTRFMODE
Hello Michael, I was able to figure out the cause of my problem. Here's the simulation workflow. 1. Run the single bunch simulation ( the script elegant.ele) to generate initial bunch and the energy profile. 2. Run the multi bunches simulation ( using bunch from step 1 to duplicate them). Somehow, i...

Re: Problems on running Pelegant with FTRFMODE
Hello Michael, After applying changes that you mentioned, Pelegant now works with FTRFMODE and single bunch. However, it still crashed when I was running Pelegant with FTRFMODE and multiple bunches, with the same error messages. In addition, it crashed immediately after the simulation reached the fi...

Re: Problems on running Pelegant with FTRFMODE
Hello Michael, This is a different issue. For this example, I set BIN_SIZE=3e-13 and N_BINS=300. If it runs fine for you, that it means something wrong with the Pelegant that I have here. Here's the error message [7] fatal error Fatal error in MPI_Allreduce: Invalid count, error stack: MPI_Allreduce...

Problems on running Pelegant with FTRFMODE
Hello, I encounter problems when I was trying to run simulations with FTRFMODE elements using Pelegant. The attached example ran fine with the serial version of Elegant, but it crashed when I was using Pelegant. The total length of a single bunch is about 2ps, so I set BIN_SIZE=0.3ps and N_BINS=300 ...
