Hello everyone,
I am new to the field of SHM and OpenFOAM. Currently, I am working on simulating the behavior of a floating body using the waveDyMFoam solver. Initially, I successfully created a mesh using SHM and simulated the motion of a 3D cylinder according to my plan. I achieved this by creating a searchableCylinder in the SHM dictionary.
However, I encountered a challenge when I tried to use the geometry by importing an .stl file of a cylinder through the triSurface feature. Although the mesh created from the .stl file appeared to be correct, the motion of the cylinder was not as expected. Instead of rotating as needed, it only moved in the direction of the waves.
I would appreciate any guidance or suggestions on how to improve the simulation using the .stl geometry. Specifically, I would like to ensure that the cylinder rotates correctly according to my specified initial angle, similar to the behavior achieved with the searchableCylinder. Thank you in advance for your help.
