Webfor further self-study. For these tutorials open source codes FreeCAD, CalculiX, FreeMAT and OpenFOAM are used. CalculiX is a comprehensive FE package covering linear, nonlinear and transient analysis. One particular benefit is that its format and structure is based on Abaqus, so knowledge gained is relevant to a leading commercial code. Web2.1 Boundary conditions 2.1.1 Inlet boundary conditions The approaching wind pro le for a neutral ABL is often modelled using boundary conditions sug-gested by Richards and Hoxey (1993). In the formulation of their boundary conditions Richards and Hoxey assume 1. zero vertical velocity. 2. pressure is constant in vertical and streamwise directions.
