FOR : Demonstration case for PHOENICS 3.3.1
VRGEOM shapemaker utility has been used here to create the geometry object representing the topography of a river course by converting BFC grid XYZ file.
The case presented makes use of the river geometry object to similate the water flow distribution on Cartesian grid.
This case deals with the 3D turbulent water flow in the river course containing two islands and having nonlinear bed topography. The free surface elevations are neglected assumed to be small for essentially subcritical flow.
The independent variables of the problem are the three components of Cartesian coordinate system, namely X, Y and Z.
The main dependent (solved for) variables are:
The plots show the flow distributions in the river course.
Pictures are as follows :
All model settings have been made in VR-Editor of PHOENICS 3.3.1
