Meshing is the process to divide the continuous domain into discrete parts to solve fluid dynamics equation to get solution of flow field and heat transfer numerically on computers. ICEMCFD is one of the leading meshing software and it is specially best for getting high quality hexa meshing for accurate CFD results.
In this course you will learn to create high quality hexa mesh with 15 high quality workshops / cases in different applications areas. You will learn to use ICEMCFD options effectively to create the blocking and also you will be able to think about the blocking strategy yourself.
Workshops/cases covered in this course are:
Workshop 1 : Geometry, domain and hexa meshing of NACA 0012 3D airfoil with different trailing edges and domain shapes.
Workshop 2 : Hexa meshing of Square Duct
Workshop 3 : Hexa meshing of cube in external flow
Workshop 4 : Hexa meshing technique for quarter cylinder
Workshop 5 : Hexa meshing of vortex generator over ramp
Workshop 6 : Transition piping hexa mesh
Workshop 7 : Hexa meshing of two type of hemispheres configuration for external flow analysis
