Dear Foamers,
i have an application that i could not find a good example for on CFDonline. i have a floating object that is allowed to move only in pitch with a lever arm from the center of rotation. and i would like to apply a torque around the center of rotation with an amplitude that is varying harmonically. I am wondering how to do that? i am using openfoam v2312 I am thinking of using the restraints of sixDoFRigidBodyMotionCoeffs. but these are the restraint types included in this openfoam version linearAxialAngularSpring linearDamper linearSpring linearSpringDamper sixDoFRigidBodyMotionRestraint softWall sphericalAngularDamper sphericalAngularSpring tabulatedAxialAngularSpring all of them are connected to implementing a spring or damper coefficients. So how can i use them to apply a force? |

i found the solution in this link:
Vary stiffness over time - sixDoFRigidBodyMotion my implementation for openFoam v2312 is attached. Last edited by AbdoMusaad; April 27, 2024 at 13:35. |
