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
