Is it possible to add partial deletion for singular species in dsmcDeletionPatch? #135

Open PrikMushi opened 1 year ago

PrikMushi commented 1 year ago

I am working on a project where I want the dsmcDeletionPatch to delete particles, but at the same time reflect some particles backwards. Is it possible to add some probability here, where some particles hitting the deletion patch do not get detelted but get reflected?

I have only one gas species in the study.

Take a look at dsmcAbsorbingWallPatch and associated mixed boundaries, e.g. dsmcAbsorbingDiffuseWallPatch.

Thank you.

From my understanding, absorbing doesn't equate to deletion from the domain? I would still like to implement something sort of deletion patch plus some particles being reflected back.

Yes, it does. For more details please have a look at the source code.

Thank you again.

I have never used the Absorption patch. Is the syntax for absorption probability as such? For 50% absorption of Argon.

absorptionProbabilities = 50_[Ar];

How to use this boundary condition? I just need to use dsmcAbsorbingDiffuseWallPatch.
