Hello everyone,

I am trying to perform a fairly simple simulation that involves the 'evacuation' of a hose (tube). Basically, the hose is made of rubber and I am giving a pressure load condition inside the tube, of -0.1MPa (negative, since it is vacuum). The ends of the hose are pinned.

For the Static step with NLGEOM off, results are being generated, and the hose is deforming. Since it is a nonlinear analysis (Rubber, non linear geometry), I used the Static Riks step with NLGEOM on.

It failed to converge, saying that Too many attemps were made for this increment.

Any suggestions would be welcome!
