The PointLocatorTree can fail if the point is only slightly outside the mesh (e.g. due to numerical tolerance issues etc). To handle this case, I generally enable out_of_mesh_mode and use set_close_to_point_tol(TOL). I typically use TOL=1.e-5, but you can set it as large as you need to.
You could try this to see if it helps for you. David On 11/13/2014 01:56 PM, Harshad Sahasrabudhe wrote: > Hi, > > I'm using PointLocatorTree to find elements containing certain points.
