Hello,


I want to simulate particles in an electrical field and have some general questions.


1) Can I use DPM to simulate particles in nanometer range, when my domain is in the size of microns? What I mean is, that a particle is much more smaller than my flow region/cells.
2) I want to include electrostatic effects. Is there any existing way, to calculate electrical fields around objects or do I need to self implement them?
3) Last question refers to 2)... How can I tell the DPM the correct vector of my E-field (with location in cell centers). What I mean is, how does DPM solver know the E-field at actual point? I know that I can define my forces by DEFINE_DPM_SOURCE. Does the solver interpolate the E-Field referring to the location in actual cell or just take the cells value?


Thanks in advance
