Problem of Complex Floating STL

Yu-Jan Wang · July 27, 2024, 01:48

Hi REEF3D Team,

I have recently attempted to import a complex STL file into REEF3D-CFD, but I've encountered a strange issue where the floating STL model rotates unstably at the beginning of the simulation. This is not entirely what I expected. If I have misunderstood something about the floating module, could you please provide me with some advice? Thank you all.

Best regards,
Yu-Jan Wang

Hi Yu-Jan Wang,

I have not had a chance to run you simulation, but what I could imagine being a problem is the missing moment of inertia. REEF3D assumes a cube when calculating the moment of inertia.
