Hello every one,

I am doing inflation analysis in Abaqus/Explicit, define the fluid cavity, cavity point and surface....i want to fill the air in pipe to have progressive inflation with cavity point as inlet point (which normally happen when we fill the air inside balloon).....but i am getting unexpected inflation pattern, such that surfaces are intersecting each other and then surfaces have their own stiffness then how does this occurring, i am attaching input file plz do have your valuable suggestions on this......
