intel and outel in teh same boundary
I have a cavity with a single enter.
So this enter is inlet and outel. I want to input a function field on the pressure, like Pinlet=cos(time), Poutlet=-cos(time).
But how can set these conditions on the same boundary?
I hope that my english is not so bad, and that you can understand me;)
Thanks for your help.
Either you split up the boundary (strongly recommended), or you can modify your field function (NOT recommended) to something like
You can also add some more conditions like $$Position (x-direction), $$Position (y-direction) etc.
When you need a circular split up, you might think about using $$Position in a cylindrical coordinate system. See the field function programming reference.
