Is it possible to solve the flow using cell size smaller than the particle size using eulerian multiphase approach?

Hi In eulerian multiphase model, it is assumed that mass and momentum are transferred on a cell-basis. So, if cell size is smaller than particle size, it means that the math is incorrect. But...
