Clarification Needed on Symmetry Boundary Condition in CFD Simulation

Hello Reef3d Team,
I'm seeking some clarification regarding the usage of symmetry boundary conditions in my CFD simulation. I have a wave tank with dimensions of 25m in length, 18m in width, and 1m in height. The main questions I have are related to placing a solid body which is symmetric along the x-axis or the length axis of the tank. Firstly, if I set one side of the flume as a wall boundary and the other side as a symmetric boundary with the dimensions of the flume being 25m x 9m x 1m, should I place the entire solid object inside the domain, or only half of it? Additionally, I encountered an issue where, when using a symmetric boundary on one side of the domain (making it half as the original), I couldn't obtain wave elevation measurements right at the symmetric boundary. If I wish to measure the elevation precisely at the center of the tank using the symmetric boundary, where should I position the probes? Another concern I have is related to exporting visualization files in ParaView. Currently, I can only visualize half of the domain. Is there a method to view the entire domain in ParaView even after implementing a symmetric boundary? Thank you in advance for your assistance. |
