LUSAS Problem

Hi, my name meizan,

I' using LUSAS for my analysis, the problem that i faced was to a surface. since my model is not square. it is curves with 5 lines. 2 curves line and 3 straight lines. when i assign the surface for meshing, the command said, it something to do with non- planar surface..

please any one help me to solve this..

thanks meizan
