Hi Jason, No, not right now. The CIC radius is always one zone. If you'd like to implement this yourself, I think the most straightforward way would be to add a derived field that implements your expanded CIC deposit kernel. Note that since this is a nonlocal deposition, you will need to create your derived field with a ValidateSpatial validator. In principle we could also add the functionality you're looking for to yt itself (although I'm not sure how we'd actually indicate the CIC radius to the user, maybe via the field name?), if you're interested in working on doing that please let me know and I can point you to resources for working on the yt codebase and instructions on how to contribute changes. -Nathan On Tue, Sep 27, 2016 at 9:35 AM, Jason Galyardt <jason.galyardt@gmail.com> wrote:

Hello yt Users,

Does anyone know whether the Cloud-In-Cell (CIC) kernel has user-controllable parameters? In particular, I'd like to be able to control the radius of the cloud for depositing particle mass onto the grid. I'm working with FLASH data, if that helps.

Cheers, Jason
