Hi Sebastian,

it's quite obvious why the dispersion is zero everywhere. The variable is initialized with zero but no value is assigned after the statistics have been computed.

Hi Sebastian,

I'll have a look at this.

Hi,

The title says it. I did simulations with the binary 2021.1 version of opal and tried to evaluate the dispersion of the beam and I got confused real quick because for all timesteps there is no data on Dispersion (i.e. the entry is zero). I can give my minimal example, though I verified it with two lattices against an older version of opal, so anyone should be able to see the same phenomenon.

I would be happy to hear if you can reproduce that error or if is indeed a problem of my lattice files. Thanks in advance!

Cheers
