- getSphKernelRadiusTimeStep(dem, cfg)[source]¶
Compute the time step given the sph kernel radius and the cMax coefficient This is based on the article from Ben Moussa et Vila DOI:10.1137/S0036142996307119 :Parameters: * dem (dict) – dem dictionary (with info about sph kernel radius and mesh size)
cfg (configparser) – the cfg cith cMax
- Returns
dtStable – corresponding time step
- Return type
float
