I have a question regarding the possibilities of creating symmetries in ANSYS Fluent.
I desire to simulate the impregnation of fibers with resin. For this purpose, I modelled a geometrically very small domain which contains the cross section of four fibers surrounded by air and the resin beneath them. Please see the image below. As you can see, the fibers are only represented by four rigid circles.
So right now my model is a closed domain, which results in the uprising of the resin level as the four cyclic walls push downwards. Of course, this model is only a tiny cutout of the real situation, in which thousands of fibers get impregnated with resin. In the real impregnation process, the rising of the resin level is nearly negligible, so for my model approach, I don´t want the resin level rising up at all when the fibers push downwards. In other words, the resin which is pushed away by the volume of the circle walls could go anywhere, left, right or downwards (trough the models walls into nirvana or something), but not upwards.
I tried to mark the left and the right wall side as "symmetry" in boundary conditions (the model is perfecty axis-symmetric), but it didn´t have the desired effect. Which didn´t surprise me either, but..
So my question to you guys is: Is this realizable or is it not? Maybe there are other ways to get the model behave as described above?
I am thankful for any input!
Thanks in advance!
