i am doing a research on an aneurysm, I want to redo an
already done work to learn details of this work. I don't know how I should set up the inlet velocity. I have the inlet velocity waveform graph from the paper, but I do not have any expression or equation which i can input into CFX. will you please guide me what I should do? I am doing my study for an aneurysm at a bifurcation of a basilar artery. I have one inlet and two outlets? I also wanted to ask what B.C i should use for the outlet. In paper, I think it mentions Newmann B.C. I have attached the picture of inflow waveform. I would really appreciate your kind help. Regards, Heasam |
The best BC for outlet is traction free kind of boundary condition. you can find many papers to find out more about this kind of BC. for inlet you can either use Pressure or womersley velocity profile which is hard to implement because cfx expressions can not recognize imaginery numbers.

Thanks alininik.
That's the problem, what would you do for the inlet BC so? I should obey the inlet velocity waveform graph? I have the data for this graph but the problem is defining a function which i can put in CFX? Regards, Hesam |
setting for blood simulation
can someone send me the setting for pulsatile blood flow simulation in ANSYS-CFX? This would be a great help to me.
Thanks |
Has anybody used UDF for womersley flow as an inlet boundary condition in Ansys FLuent. IF then if can you share here.
