# Tutorial - Solving 2D Truss problem using Mechanical APDL (ANSYS)?

This is our problem which we are going to solve. In initial step we will identify the keypoints. The keypoints are

1. 0 0 0

2. 3000 3000 0

3. 6000 0 0

4. 0 3000 0

5. 6000 3000 0

6. 3000 6000 0

7. 0 6000 0

8. 6000 6000 0

9. 0 9000 0

10. 3000 9000 0

11. 6000 9000 0

12. 0 12000 0

13. 3000 12000 0

14. 6000 12000 0

15. 3000 15000 0

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

We will go through these and solve the problem. I will suggest you to go through this tutorial before solving this problem. http://grabcad.com/questions/tutorial-2d-truss-analysis-in-mechanical-apdl-ansys-part-1
