placeParticles(hCell, aCell, indx, indy, csz, massPerPart, nPPK, rng, cfg, ratioArea)[source]

Create particles in given cell

Compute number of particles to create in a given cell. Place particles in cell according to the chosen pattern (random semirandom or ordered)

Parameters

  • hCell (float) – snow thickness in cell

  • aCell (float) – cell area

  • indx (int) – column index of the cell

  • indy (int) – row index of the cell

  • csz (float) – cellsize

  • massPerPart (float) – maximum mass per particle

  • nPPK (int) – number of particles per kernel radius (used only if massPerParticleDeterminationMethod = MPPKR)

  • cfg (configParser) – com1DFA general configParser

  • ratioArea (float) – ratio between projected release area and real release area (used for the triangular initialization) limitations appear if there are multiple release areas feature (the ratio stands for the average of all release areas so it is not specific to each feature).

Returns

  • xPart (1D numpy array) – x position of particles

  • yPart (1D numpy array) – y position of particles

  • mPart (1D numpy array) – mass of particles

  • n (int) – number of particles created

  • aPart (int) – particle area
