OK, so that's a bit more difficult. Hence my questions.Â
Modelling the bulk filter would use porous media and you'd just have to assume it worked but would be interested in pressure loss & velocity to improve system energy efficiency and avoid damaging the filter.Â
Modelling separation by particles hitting fibres and forming a cake is much more complicated. If you can neglect the flow then Rocky (alone) is a good option. If you need include the flow it's messy and would need much more thinking: Rocky & Fluent would be coupled but there are size considerations to figure out.Â
