How to create Infiltration raster from Land Cover and Soils rasters
First, you need to create:

How to import Soils Data
RAS MAPPER | Map Layer | Right click: Create a New RAS Layer | Soils Layer
RASter Calculator for WSE Comparison
1. Check the results of the WSE (Max) you want to compare. If they are not visible, you cannot compare them with the RASter Calculator.

Unsteady Computation Options and Tolerance
Timing Parameters - Courant Numbers
Under the SWE-ELM modeling approach, we should be setting the maximum courant around 0.8 to minimize flashiness of the hydraulics in the 2D model domain. Here is the set of parameters that typically gives smooth results:
