UDF Boundary Condition
When using a UDF to implement a BC does the profile have to be a continuous function or can you insert specific points on the boundary and have Fluent fill in the gaps.
Thanks for your help |
Re: UDF Boundary Condition
I do nto think u can think of FLuent filling the gap. You have two options:
(1) define a profile (2) read data from a file for the mesh points I donot think any other method works. Murali |
Re: UDF Boundary Condition
You can interpolate your data and implement the equation you obtained in a UDF.

Re: UDF Boundary Condition
Maybe you do not explain your problem cleasly. if you want to define a function along the boundary, it is simple. if you want to define an incontinuous boundary condition on the two sides of the boundary, it can be implemented by UDF.

Re: UDF Boundary Condition
Thanks for your help. What I have is a 2-D boundary plane on which I will know velocities at cerain points in a grid taken from experimental data. From what you've said I will use a math program to create a function from the velocities and then use a UDF to implement it, unless someone knows of a better way.

Re: UDF Boundary Condition
you can give your data points through piecewise linear function.. But I dont know how actually works.. c the fluent manual for B.C.
