access to FIDAP-internal data from within a UDF II
 
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

Re: access to FIDAP-internal data from within a UD
 
if you define your entity as slip you can automatically define boundary condition in terms of local coordiates: T1, T2, N3
