Hi Michele, Extending data library should be possible with 2 major constraints. First constraint is that it takes some time as I have to generate a large amount of geometries for building the tables. Also, I try to support both 2 terms and sinus modulation profile, as well 4 rods and 4 vanes structu...

Hi Toutatis will save one distribution every cell, sorry. In case it would help, you can finish earlier the simulation with the command "RFQFinish z". Toutatis will run until the last particle in the bunch passed through the z coordinate in meter. By doing this, you should get a .plt file with all c...

Bonjour! To export particle distribution along the RFQ, the solution is to set .plt export in .inp file with the command COMPRESSION_FACTOR ncompress. ncompress gives the data resolution in .plt file as follow: if (ncompress==0) { // float (32 bits) cc1=125; cc2=100; } if (ncompress==1) { // short i...

Hi Not sure I can help but I will try first to clarify the statement of the problem. First TraceWin does not generate fielmaps but Toutatis does either as a standalone code or as a library within Tracewin. I guess your colleague managed the second case. Depending on how were the settings used by you...

Hi I don't know if it was tracking fine but what I have noticed is that you triggered a bug in the code as Toutatis was trying to generate a field map all along the anticipated bunch path and this reference path and the 3.6 MeV bunch path were too different. This made that the code tried to export f...

Hi

while I was debugging your case, I just realized reading your dst file with Plotwin that you inject a 3.6 MeV beam into a RFQ made for 75 keV. I guess you are trying to use the wrong file as input.

OK. I am on it. Meanwhile, if you just want to get a field map, as you mentioned, use theDistribution k instead.

Anyway, I am trying to find the issue.

Hi

Thx. I will investigate this.

Hi I have no problem running the code with your input files but the .dst. At the moment I use your .dst file, the code freezes. When I try to open your .dst with Plotwin, I get the error message in the attached picture. Please consider revising your dst file and check it before runing Toutatis with ...

Hi If NBRMSCELL 4 then cell0 to cell3 will be considered as cells in RMS. If I remember correctly, the cells parameters in .inp are considered in general at the middle of the cell. Also for the RMS, the vane profile in RMS will finish at R0, R0 being the value given for the cell after the RMS. To be...
