How sub-mesh works in Flow-3D sediment scour model for estimation of bed-load transport?

Flow-3D sediment scours model manual (Wei et al., 2014) mentioned that a sub-mesh is applied to calculate bed-load transport. Other details are not available that how this sub-mesh works between...

Why Flow-3D sediment scour model can not caputure exact morphological features in mobile bed channel?

When we are dealing with a non-bridge pier scour problem e.g. meandering channel. The exact location, shape, and dimensions of scour hole and other morphological features like deposition bars in...

How to decrease the mesh skewness problem in OpenFOAM and other simulations?

Skewness is defined as the difference between the shape of the cell and the shape of an equilateral cell of equivalent volume. Highly skewed cells can decrease accuracy and destabilize the...
