WEEK 2 DAILY SCHEDULE:

Tuesday:
8AM: Begin first Tutorial from Cornell:
1) Flat Plate Boundary Layer
https://confluence.cornell.edu/display/SIMULATION/FLUENT+-+Flat+Plate+Boundary+Layer+-+Problem+Specification
Key Points to take away:
Geometry-surface from sketch
Meshing-edge sizingWhat is a Bias Factor? The ratio of the longest division and the shortest divisionFluent- 64 bits for double precision and 32 bits for single-precision The downside of using double precision is that it requires more memory.Fluent- Plotting from Blasius direct theoretical solutionWhen Plotting make sure to rename whatever plot ending in “.xy” as you plot in the XY PLOT section
2) Steady and Unsteady Flow past a cylinder

Batch Mode in FLUENT- use C++ to write/compile the files-Look at the pdfs I gave you. One of them is on BATCH mode for an earlier version of FLUENT. Shouldn’t be too different with ANSYS. Read in a journal file with commands given in a precise order for your particular model. Sit back, drink a cup of coffee.
Bash in Linux- execute the Batch commnads

CFD FLUENT Research Tutorial on transient Couette flow over a grooved surface
Do the prescribed tutorials mentioned above. Even the structures based tutorials. It is very important for the user to be proficient with the geometry modeler and meshing program in Ansys. These two programs are used for building the model and the mesh used in the analysis, and there is no room for error.
Spend at least two to three days, if not a full week, on learning the Ansys 13 program and finishing all of the tutorials. Afterwards, begin research project.
