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
geometry- create surface from sketch. 2D modelBoolean operation (subtration-create)-outer surface body as target body inner surface body as tool bodySketching line on y-axis of both circles and trim away outer and inner part to creat two linesconcept--> line from sketch to create the line body tools--> projection for surface body as target and two lines as the edgeMesh-18432 elements 192 circumferential divisions;96 radial divisionsMapface meshing/ Biasing to increase number of elements close to cylinderRadial edge sizing; type=number of divisions=96Behavior=hard; Bias type=___ __ _ Bias factor= 460Create named selections: farfield 1, farfield 2, cylinderwall and in fluent it creates the interiors themselves.Fluent: cylinderwall=type=wallfarfield= type=velocity inlet=1m/sfarfiled2=pressure outletinterior surfacebody; surface bodyReference value=density=1kg/m^3viscosity=0.05kg/m*smomentum=second order upwind schemeResiduals--> xvelocity=1e-6; yvelocity=1e-6 (for absoulte criterion)Monitors=Drag=EDIT=print to console and plotsolution initialization=1m/s (x-direction)number of iterations= 2,000solution converged after 1647 iterations.

Now, have a bottle of Mountain DueContinue time stepping until you get sinusoidal variation in the lift coefficient
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.
In the edevauer of creating a 3D simulation of the butterfly in the CFD solver FLUENT much was learned such as the following: Flate plate boundary layer, simulations, Steady flow past a cylinder simulations,
