Hi, I'm Edoardo and I'm attending the last year of Space Engineering. For the Space Structures Laboratory, I'm simulating the modeling of membranes and the wrinkling phenomenon (solar sails). However, I'm having a lot of problems with patran, most of them are related to convergence problems.
I know that there are a lot of pdf talking about it but I need some advice.
One of the papers that I'm following is about a membrane under a shear load (Pellegrino). In patran, I created the points, the curves, the surface , the material (isotropic kapton), the property (2D shell) and then I applied as boundary condition an encastre at the bottom edge, a displacement of 0.05mm along the y axis at the upper edge (in order to pre-tensioning the membrane) and, for the next subcase a displacement of 3mm along x axis in the upper edge.
For the analysis, I used the sol400 with a linear static step for the first subcase and a buckling step for the second subcase. However, I've different fatal error.
Someone can help me? Thank you very much!
