Hi everyone..
Can we give our own Boundary Conditions in FLUENT other than the boundary conditions that it contains by default. |

You should be able to define the BC you need in the options. Otherwise you may need to program a User Defined Function to do whatever it is you want.

Yeah, UDF's are made in C, so you'll need to read up on user defined functions in general. You'll probably want to use DEFINE_PROFILE, and there are some nice examples that make use of that command if you read the user defined function guide. You could easily modify their code to make the BC you want (most likely), but it is going to take a few hours of reading the udf manual to understand it.
http://www.hipecc.wichita.edu/pdfs/fludf.pdf (courtesy of Wichita State University, but syntax may have changed a bit if you're not using Fluent 6. Read section 8.2 for an example of a UDF boundary condition.) |
