1 Serial UDF on Windows OS

Note:

• Udf has to be compiled, can’t be interpolated

Steps:

1. launch Fluent from the Command Line

For ansys 16.x, launch Fluent from the Command Line using the VS2015 x86 x64 Cross Tools Command Prompt (not x64 x86 cross tools)

• Open the Start screen (press Windows button on your keyboard, Type 'VS2013 x86 x64 Cross Tools Command Prompt'
• change directory to your working folder, e.g. cd C:\Users\exw692\kaiming\Shared\ch6_wave_effect\OldGeo\e387UDF\sine
• Type “fluent” in the command window to launch Fluent or “C:\Program Files\ANSYS Inc\v161\fluent\ntbin\win64\fluent.exe” (quotation signs included, in case of standard installation; fluent version: 16.1).

Make sure that on the Environment tab 'Setup Compilation Environment for UDF' is ticked. The default address is fine.

1. Read mesh/cas file
2. Setup turbulence model/boundary conditions, etc.
3. Compilation Define/user-defined/functions/compiled, load
4. Hook UDF file to velocity component at inlet Boundary condition/inlet/x or y component velocity/udf
5. Setup point monitors at inlet Create a point at inlet and monitor the velocity at the defined point

To create a point at inlet BC

Surface/point Solution--monitors--surface--fill your information to dialog table

Report type: vertex average

Field variable: velocity, velocity magnitude/component;

Surface: a point at inlet BC

1. Setup time step size, 0.002s, save cas file Time step, 1/100 period of wave

   1 degree per time step, 0.001s, 360 time step per circle of turbine rotation

ω=2*π/T

If ω=14.34, TSR=5.5, T=0.44,

U(m/s)	TSR	r(m)	Angular velocity	T(s)	time step size
0.6	5.5	0.23	14.34782609	0.437919 0.001216

1. Initialisation, compute from inlet
2. Calculation, 200 time steps
