Hey there
First of all, I hope this is the appropriate forum. From the descriptions provided here, I didn't find a more suitable sub-forum. Now a little context to my question: I'm a master student and I'm preparing my thesis right now. The topic is a numerical simulation of propeller-induced erosion on river beds, which has to be conducted with OpenFOAM or foam-extend. For this, I installed Xubuntu 16.04 on my laptop and compiled foam-extend 4.0. I did the three tutorials (cavity, plate with a hole and dam break), but apart from that I'm completely new to OF. As typical for a master thesis, I only have a limited amount of time, so time-efficiency is one of my major concerns. Any advice on that aspect are welcome, if it's not "Don't use OpenFOAM then." I looked into the specifications of four different models (or modules? Please correct my wording if necessary) that might be used for my simulation, which are the following:
The first two are couplings between CFD and DEM, and I guess that also applies to the third - or is that only DEM? The last one models the sediment as a highly viscous fluid, though I didn't even get the exact difference between that and just TwoPhaseEulerFoam. Now my big questions are the following:
Any answers, hints, advice would be very much appreciated. Thanks in advance, L. |
