ana5Utils.distanceTimeAnalysis.approachVelocity

approachVelocity(mtiInfo)[source]

compute maximal approach velocity based on front location (range) and time step

  • cleans nan in range

  • neglects anything behind maximal runout

  • neglects non-unique range values, e.g. the front did not move

  • cleans approach velocity: velocity in cell under test can not be higher

    than the double of the mean from the surrounding cells

Parameters

mtiInfo (dict) – info on distance to front and time steps

Returns

  • maxVel (float) – max value of approach velocity

  • rangeVel (float) – range of max value of approach velocity

  • timeVel (float) – time of max value of approach velocity
