Dear Michael, I have compared the simulation results with Eq. 9 of Zhirong's paper and the new code produces result similar to the theoretical prediction if Coulomb Log=3.44, which corresponds to 1.6e-3 relative energy change cut-off in the core of the distribution! Thank you. I however have an issu...

Michael, Thank you so much. I have managed to download the new version (I was getting download fail message for some reason) and run my test again (attached): Long case: 9m drift + IBS Short case: 0.9m drift + IBS section repeated 10 times Ultra-short case: 0.09 drift + IBS section repeated 100 time...

Dear Michael, I have sent you and Bob an email with all relevant files on October 10th. It has wakes and Genesis-like files of the distribution used with an output of sddsanalyzebeam command. Here I can share my simple example of the issue I am having in my calculations: ++++++++++++++++++++++++++++...

I am now convinced that IBSCATTER element is broken. I have tried a simple 9 meter drift for 100 pC bunch at 150 MeV with IBSCATTER elements included at different separations. A single IBSCATTER element at the end of 9 meter section gives the largest energy spread increase. Placing 10 IBSCATTER elem...

Hello, I am having an issue with IBSCATTER element in my beam line: q: charge, total=1e-10 samp: sample, fraction=1 cav2_c: rfcw, L=0.0526, CELL_LENGTH=0.0263, & N_KICKS=2, CHANGE_P0=1, & ... cav_c: rfcw, L=0.4997, CELL_LENGTH=0.0263, & N_KICKS=19, CHANGE_P0=1, & ... cav_h: rfcw, L=0.4471, CELL_LENG...

Michael, Thank you for your response. I agree with you regarding threads vs cores in general. In this case however, the performance improvement stops at 8 processes while I have at least 24 physical cores with my dual socket E5-2687W v4 processors. I have just run the simulation with 0.001 particle ...

Hi Michael, My system has 128 GB of memory, same as the other workstation I am benchmarking against, while the simulation takes only <15 GB. So , I am safe as far as being low on memory. Yes, I run my simulation with print_statistics=1. It does not give me enough information to diagnose why my syste...

I am a brand new user of the elegant and need to use it in order to study microbunching instability of ultra bright beams in x-ray FELs. I have .ele and .lte inputs to start with. I have installed March 7th, 2019 version and then updated April 1st, 2019 version of Elegant_x64.msi on Windows 7 with M...
