I am trying to build a 2-d modeling for the cylinder problem. In order to differ it from the 2-d plate probelm, I treated it as Axisymmetry in Solver, how ever after initializing, and solving, the error information occured: " No positive volume exists".

So my question here is " technically in 2-d geometry, how can treat the rectangular geomatry as it in cylinder configuration?"

Thank you so much!!!!

gang,the pipe or the rectangular are 3D,you can not deal with them use 2D model.
