Errors - Reinforced Concrete Beam
Attached are two errors that I encounter when modelling the beam using the Finite Element Method (FEM). May I ask for some suggestions and help with those problems?
The first error is regarding the converge on a solution for the nonlinear problem. May I know why will this happen and how to solve it?
The second error is regarding an internal solution magnitude limit was exceeded. Is that mean that the load applied to the beam was too large or exceed the ultimate load?
Thank you in advance.
