Hi everyone,<\/p>\n

I am trying to simulate the deployment of cylinder using a Static Structural analysis of Ansys Workbench with a linear elastic material. I have no experince with shell elements so I am having trouble implimenting them. I found that Shell181 is a usefull membrane element when large deformations occur, since I also want to neglect the bending of the elements. <\/p>\n

When applying radial pressure to the cylinder I get a Solver Pivot Error.<\/p>\n

I attach below the way I applied the membrane elements and the error I get.<\/p>\n
