    In general, a finite element solution may be broken into the following three stages.
    1. Preprocessing: defining the problem;
    - Define keypoints/lines/areas/volumes
    - Define element type and material/geometric properties
    - Mesh lines/areas/volumes as required
    2. Solution: assigning loads, constraints and solving;
    3. Postprocessing:
    - Lists of nodal displacements
    - Element forces and moments
    - Deflection plots
    - Stress contour diagrams

    In this tutorial we will go through second and third step.

    1. Step 1

      This is the second part of tutorials in Which we solve the problem. Under Solution >> Analaysis Type >> New analysis. Select static and click OK.

      Medium

    2. Step 2

      Under Define Loads >> Apply >> Structural >> Displacement >> On keypoints. We will now define the fixed keypoints or supports.

      Medium

    3. Step 3

      Select the two lower corner keypoints and click OK.

      Medium

    4. Step 4

      Select All DOF and click OK.

      Medium

    5. Step 5

      Goto Define loads >> Apply >> Structural >> Force/Moment >> On Keypoints.

      Medium

    6. Step 6

      Select the upper keypoints and click OK.

      Medium

    7. Step 7

      Direction of force be FY and input Force value = -10000 since the force will be acting downward.

      Medium

    8. Step 8

      Now we have the model prepared for solution. Under Solve >> Current Load step.

      Medium

    9. Step 9

      Click OK.

      Medium

    10. Step 10

      A message Solution is done! will show when the process is completed. Click Close.

      Medium

    11. Step 11

      Now the third part of this process. Post-Processing is to be done. Goto General PostProc >> List Results >> Reaction Solu.

      Medium

    12. Step 12

      Select all items and click OK.

      Medium

    13. Step 13

      Now we have the value of reaction about the node 1 and 5 which are fixed. Click Close.

      Medium

    14. Step 14

      Goto Plot Results >> Deformed shape.

      Medium

    15. Step 15

      Select Def + undeformed. Click OK

      Medium

    16. Step 16

      Now we have the deformation plot.

      Medium

    17. Step 17

      Goto Plot results >> Contour plot >> Nodal Solu.

      Medium

    18. Step 18

      Under Stress select von Mises stress and click OK.

      Medium

    19. Step 19

      We have von Mises stress plot.
