Hi Array : I got the same result 970 N.nYes, I run a beam model in a beam analysis package, but the results should be the same irrespective of the method. Also, I am aware of the mathematical formulation of FEM and that the resolution of the matrix is in the nodes. So, I expected the reaction in the node to be the same than I manually solved. I attach the model, maybe you can have a look and see if you and me are doing the same resolution because maybe this is just what is wrong in my model. Thank you!nnArrayPD:Just to say that:This is one example we run at class with the strudents, so I want to understand what's going wrong in my FEA model n
