Time varying parabolic velocity

fcortes · September 27, 2010, 22:14

Hello FOAMer friends. This is my first post, I'm new at this forum and also new in the use of OpenFoam. I'm working on my mechanical engineering thesis and I have to simulate a pulsatile blood flow in a vain. In order to do that I need to set a parabolic velocity inlet, but one in which the maximum value fluctuates in time. I did implement a parabolic inlet and a timeVaryingUniformFixedValue, but I haven't been able to mix the two boundary conditions, actually I don't know how to do so.
Any help will be appreciated, I've been stuck in this for a couple weeks now and I'm quite lost.
