23.7.9 Postprocessing of Erosion/Accretion Rates

You can calculate the erosion and accretion rates in a cumulative manner (over a series of injections) by using the Sample Trajectories dialog box. First select an injection in the Release From Injections list and compute its trajectory. Then enable the Accumulate Erosion/Accretion Rates option, select the next injection (after deselecting the first one), and click Compute again. The rates will accumulate at the surfaces each time you click Compute.

Both the erosion rate and the accretion rate are defined at wall face surfaces only, so they cannot be displayed at node values.
