Tutorial: How To Obtain Relative Accurate Results From Stress Analysis in Autodesk Inventor

FEA is not a simple mathematical operation. Instead it is a computer-based iterative numerical technique along with inevitable discretization errors, as a function of elements. Therefore these errors can be reduced by... specifying more elements (H-refinement) or employing a higher order of polynomial at each iteration (P-refinement). Effectively more computational power is required to solve complex shaped geometries with high dense mesh (Elements). But how dense should be my mesh to get appropriate results without wasting hours on simulation ??? This is the Golden Question! ... There is a criterion for that, called Converged solution... In plain words the mesh does not need any further refinement (denser mesh) as long as the solution is "Converged". The solution is assumed to be "Converged" when the results of the polynomial eq. does not change according to a prespecified tolerance e.g. 10% Good Results, 0.1% Great Results. So, let me share some information how to manipulate the mesh for a model along with three examples. As a conclusion we will enhance your confidence regarding the results you get, whether are relatively accurate or not (Low Percentage of Discretization Errors) without wasting hours on simulation!!! Don't Forget the simulation results are nothing without any experimental results to compare with.

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

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

This video has the complete solution to CSWP-MM examination available on official website of SolidWorks. I have explained each and every step to achieve the solution. One of the issue that most of the users have faced is in the question 2. Correct answer is 17 negative faces while that is not achieve in most of the cases.
