Using ANSYS, plot the deflection, bending moment, and shear force distribution of the beam. If you have four elements, what is the optimal mesh? Repeat the solution with an eight-element mesh. Comment on the results. Is your solution right? How can you improve the finite element solution? 

  1. If your model is not sufficiently constrained, you'll get a solver pivot error since the algebraic equations generated will not have a unique solution. What are the displacement and rotation constraints that need to be applied in your ANSYS model so that you don't get the solver pivot error? 
  2. What is the total no. of degrees of freedom that ANSYS puts in for the four-element mesh?
  3. Bending moment: Trend from A to B
    a. Do you expect linear, quadratic or cubic variation?
    b. Does the ANSYS solution within each elementshow element show this trend? Why or why not?
