access to FIDAP-internal data from within a UDF II

April 23, 2001, 02:38

Hi everybody,

as I already mentioned in my message from April 17, I'm having a problem with the definition of boundary conditions in FIDAP. Since nobody posted an answer so far, I suspect that my explanation wasn't clear enough - sorry for that. Here's my second attempt:

I'm trying to compute an internal flow where the boundary condition to be applied at a wall node depends on the local tangential direction of the wall with respect to the global XY coord. system. That is, I need to know the local slope of the wall with respect to the XY coord. system. Can FIDAP give me this information?

Once more, thanks in advance,

Ingo Meisel

if you define your entity as slip you can automatically define boundary condition in terms of local coordiates: T1, T2, N3
