 November 18, 2010, 23:52 movingCone with sliding boundary #1 Senior Member   Daniel Join Date: Jul 2009 Location: Montreal, Canada Posts: 151 Rep Power: 8 Hello all, I am conducting a simulation with an oscillating airfoil, and I would like to make the grid points on the outlet of the C-grid move up/down in concert with the trailing edge of the oscillating airfoil, to improve mesh quality. Essentially, I am trying to implement the same feature as the movingCone tutorial, where the points above the cone are stationary relative to the cone during the cone motion. If that was my simulation, it would be as if the cone moved, but the grid points above the cone remained stationary, greatly distorting the mesh. Thanks in advance, Dan

I'm trying to do the same (in the rotating square), but just the upper and lower boundaries slip. How can I make the left and right boundaries slip also? I think that's what you did in your case and worked! Regards

I'm afraid I don't know why that would happen. When I say that it worked for me, I mean that the points are moving in the far field at the boundary, but I still have mesh quality issues with the rotating body at the body boundary. No solution yet, unfortunately. Dan

 July 30, 2013, 09:29 moving cone problem (pimpleDyMFoam) #6 Senior Member   kumar Join Date: Nov 2011 Posts: 115 Rep Power: 5 Hai Dan, 1.) In moving cone problem (pimpleDyMFoam), Is there any possibility for continuous translation motion? (ie) left to right 2.) Is there any mathematical equation for that? How I can Proceed, kindly guide me __________________ kumar
