      Hello,

      I'm trying to output data from my hypervelocity impact simulation, specifically the momentum of each particle. Is there a way to track and store the momentum of each SPH particle?

      Thanks,

      Conor

      , you could do this by entering an equation by query via user defined result.
      VSUM gets the Velocity of the Nodes of SPH body (by Scope) and MASSALL gets the Mass of the node in SPH , by momentum equation m*v which yields your answer, Add to this, you can also do VX,VY,YZ to study the Directional momentum to suit your study
      Cheers, Ram
