Dear all, currently I'm modifying the wingMotion case in the tutorial to a 2D circular cylinder. The main work in the modification lies in the pointDisplacement file. The cylinder is supposed to vibrate only in the y-axis(due to lift force). So I used the following lines:
Code:
constraints { maxIterations 500; fixedLine1 { sixDoFRigidBodyMotionConstraint fixedLine; tolerance 1e-9; relaxationFactor 0.7; fixedLineCoeffs { refPoint (0 0 0.025); direction (0 1 0); } } } restraints { verticalSpring { sixDoFRigidBodyMotionRestraint linearSpring; linearSpringCoeffs { anchor (0 0 0.025); refAttachmentPt (0 0 0.025); stiffness 6; damping 0.1; restLength 0; } } } What does this message mean?? |
