Particles are not uniform when Surface injection are used.

    • 2019023289

      Hello, could you please tell me how to make particles evenly distributed at the entrance? Now I use surface injection,My mesh is not uniform at the inlet, and the number of particle parcels is determined by the number of grids, which are injected from the grid.So the particles are not uniform when they come in.This is the volume fraction of particles, and there are many mesh dense particles at the inlet (particles are distributed according to the distribution of mesh density). If Surface injection mode is adopted.I know that file injection can be customized, but my calculation is unsteady, and I am not familiar with file injection.And I use group injection type,it diverge.

      Please check following help manual. 

      It has format for unsteady.

      To add, read the definition of DPM Concentration carefully: it's not quite what you think it is.
