Hi Alejandro,rnrn1/ For it you could have a look at our phaseSeparationXd examples. The singe component, multiply phase model could be used for it. This is like VOF rn2/ We have resolved particles using two way coupling as well as Lagragian particles (LBM-DEM). However, this is not available at the moment. If you are interested in it, please contact me using the contact form.rn3/ Please have a look at the nozzle example. There are 3 models whoch can be used. Mind that OpenLB can be extended easily.If you need help, please, also conatct me.rnrnBest regardsrnMathiasrnrn
