DEVELOPMENT AND APPLICATION OF A CFD MODEL OF LASER METAL DEPOSITION

You can download phd thesis on the above topic from here https://dl.dropboxusercontent.com/u/...datastream.pdf

Here you can find the difference between different techniques and how they help you to achieve faster convergence.

Rule of thumb:

1. Use the mesh generator which is being used by your friends who are available to help you out.

2.Best sotware in market is ICEM (Hexa), but it is difficult to learn and takes alot time in mastering. Its tetra + prism version is very efficient and easy to use.

3. Ansys meshing is new technology and very easy to use.

4. Gambit is very easy to learn and its tetra with boundary layer (in 3d implementing boundary layer often...

What is the physical significance of both options. When to use static pressure (fixed every where) and when to use the Average static pressure(floating with average constrained)?

In my opinion static pressure condition may be the good for the boundary far away from the object to be studied, in other words flow is more or less uniform at outlet boundary.
On the other hand the average static pressure may be more physically correct as it allows the conditions to vary along the...

In this thread, I have discussed different issues in meshing and geomtry importe related to radial turbochinary. Geomtry and blocking is also posted here. Feel free to use geomtry and blocking and let me know if you have any diffciultly to handle these type of geometries.
