Dear all,

From CST I can export a particle distribution. In contrast to OPAL (and propably most of the other available simulation codes):
CST weights the macro particles by different macro charges instead of having the same macro-charge for all particles. The number of particles is (almost) equally distributed (slightly influenced by the simulation accuracy).

I am thinking of a way to convert the CST distribution to one, that can be used in OPAL (using FROMFILE).
Has anyone faced this task before and has a method/script that (s)he might share?

[I've looked into the python script by Bettina Kuske and Dieter Faulbaum (HZB), that converts an ASTRA distribution to OPAL, but it's unfortunately not suitable as ASTRA has a const. macro-charge for all particles, right?]

Thanks again in advance.

Best regards,
Simon

P.S.: I am sorry, that I've opened a second request mail, but being able to convert CST distributions to OPAL would circumvent the DC acceleration problem (see my last listing mail) for now.
