Hello everyone
I have problem to obtain the mesh model for this surface: http://www.polne.net/AD/pipe_wall.jpg http://www.polne.net/AD/pipe_wall2.jpg This object is a pipe wall treated as a boundary layer for the fluid region. On the photos we can observe fluid region (red) and the another region (structure). I have introduced: - default face spacing: option-angular resolution, angular resolution-18 degrees, min edge length-0.1 mm, max edge length-4.5 mm, radius of influence-0mm, expansion factor-1.2 - inflated boundary option: number of layers-5, expansion factor-1.2, number of spreading iteration-0, min internal angle-2.5 degrees, max external angle-10 degrees, option-first layer thikness, define first layer by-first prism height, first prism height-0.01 mm, extended layer growth-yes, layer by layer smoothing-no. The length of the model is 50 mm, and the width is 25 mm. I have problem to obtain mesh due to: - boundary edge does not exit face (Subr: cutlist), - mesh spacing does not adequately resolve CAD face and results in self-intersecting boundary edges, - parameterization of faces poor near singular points. Any ideas how to mesh it ?? regards nasdak |
