Hello,
I am currently using GeoDict (FilterDict module) and I have a question regarding the temporal resolution used to integrate the particle equation of motion in a Lagrangian framework.
I could not find clear information in the documentation about how the time step is defined or controlled when solving the particle equation of motion. Is the time step fixed or adaptive? And where can this information be accessed?
In addition, when visualizing particle trajectories, I noticed that a spatial resolution of 0.5 voxel is used by default. Is this parameter related to the temporal resolution (time step), or is it only used for visualization purposes?
More generally, how can one assess the accuracy or convergence of particle tracking simulations with respect to the time discretization in GeoDict?
Thank you in advance for your help.
