Support node at the intersection of a panel and lline

Anonymous — Thu, 14 Nov 2013 14:39:58 GMT

Hi,

I am trying to model a curved panel in finite elements. To make things more simple, I've made a discrete polyline of this curve and then made the panel from an extrusion of this polyline.

I am then trying to put support nodes on this panel. The nodes are created by intersecting horizontal lines at the right height and the polyline (edge of the extrusion), so their coordinates have to be just right inside the plane of the panels.

My problem is that when I generated the mesh (Delaunay + Kang with refined mesh on support nodes and emitters), the previously created nodes are not taken into the mesh.

I guess that's a problem of tolerance, but I can't figure a way to force these nodes to be considered into the mesh.

Thanks.

Regards.

Extruded , revolved panels do not consider user nodes in meshing. You have to either create wall(s) as ordinary panels or freeze meshes and move nodes

Thanks, it actually works ok by creating standard indepedent panels.
