It Is a simple cantilever beam model with a rectangular section. Fully fixed in the left side (roations zero and displacements zero or fixed, which has the same results) and an articulation in the middle (only fixed displacements in y). A force in the right side. The horitzontal reaction in the fixed left side should be (theoretically) 1000 N (down) and ANSYS give me 969.99 N (down). Othe resullts such as the moment and the maximum displacement are not the same than the theoretical. I checked the model in other softwares and I got the same results than the teorethical. Therefore, the problem I have is in the ANSYS model.nn
