Dear all,
I'm using waveDyMFoam solver with sixDoFRigidBodyMotion option, to study a rotating device moving in water. I would impose a constant torque to the shaft: I added the line with torque string in the "dynamicMeshDict" file , but it seems that the defined torque is used only as an initial condition and not as a constant value imposed. Anyone know the reason of the error and how to fix it? Many thanks in advanced. Code:
sixDoFRigidBodyMotionCoeffs { patches (rotatingWalls); innerDistance 0.3; outerDistance 1; centreOfMass (5.0 -0.14 0.0); mass 0.000432; momentOfInertia (0.0 0.00000023 0.00000023); orientation ( 1 0 0 0 1 0 0 0 1 ); torque (0 0 1); rhoName rhoInf; rhoInf 1000; report on; accelerationRelaxation 0.08; // 0.1; value uniform (0 0 0); g (0 -9.8 0); constraints { rotationAxis { sixDoFRigidBodyMotionConstraint axis; axis (0 0 1); } fixedPoint { sixDoFRigidBodyMotionConstraint point; centreOfRotation (5.0 -0.1 0.0); } } |

I think it should be defined under entry 'Restraints'.
However I am not sure how to make the resistant torque constant. |

Hi everyone,
I am having a problem using matlab in openvibe. I followed the steps mentioned in the tutorial but still getting an error. For example, when trying to implement tutorial 2, this is what I get. What do you think?? |
