  You need to code it again as an additional force which you can then store for each particle as particle scalar

  Thanks´╝îDrAmine. Programming Brownforce with UDF? And then export it? How should I do?
  And Can I get the momentum exchange between the particle and the fluid´╝ƒI know the formula for momentum exchange between particles and fluid. Can I use this formula to define an expression in CFD-POST to calculate the specific value of momentum exchange´╝ƒ
  Really Appreciate.
