It is simple now to find the limit of materials and how to make a part without strkctural problems. Now you should apply a material, in my case Steel. A very important thing that you must know is to find the Proprieties of a material. The size is represented with green and the sag with blue.

The explanation of these elements is: I have some more points regarding the mesh size. As indicated earlier, a smaller mesh could result in a more accurate solution; however, this cannot be done indiscriminately. The elements must be small in the regions of high stress gradient such as stress concentrations. These are areas where the geometry changes rapidly such as bends, fillets, and keyways.

Uniformly reducing the element size for the whole part is a poor strategy. This means that the boundary conditions cannot be applied to nodes and elements. The structurzl conditions can only be applied at the part level. As soon as you enter the Generative Structural Analysis workbench, the part is automatically hidden.

Therefore, before boundary conditions are applied, the part must be brought to the unhide mode. This can be carried out by pointing the cursor to the top of the three, the Links Manager. Analywis FEA, restrains refer to applying displacement boundary condition which is achieved through the Restraint toolbar. The Clamp conditions mean that the displacements in all three directions are zero.

In FEA, loads refer to forces. The Loads toolbar is used for this purpose. Select The Distributed Force icon, and with the cursor pick the face that you want to be loaded.

When you put the force be attention when you chose the direction of it. In my case, because the front face is not in total contact with my force, I made in Part Design module a simple Pad, with 10 mm larger than the hole with only 0. My Distributed force is N.

To run the analysis, you need to use the Compute toolbar by selecting the Compute icon. In the Compute box leave the defaults as All which means everything is computed. To view the deformed shape you have to use the Deformation icon.

The resulting deformed shape is displayed below. The deformation image can be very deceiving because one could have the impression that the wrench actually displaces to that extent. Keep in mind that the displacements are scaled considerably so that one can observe the deformed shape. Displacement — is available on Image toolbar. The default display is in terms of displacement arrows as shown on the right. The color and the length of catai represent the size of the displacement.

The color legend indicates a maximum displacement of 0. Von Mises Stress is also on Image toolbar.

The von Misses stress is displayed to the right. The maximum stress is 4. When you want to save Part and Analyze you should use Save management. Very nice post, thanks. Are there any parameters to adjust to have those areas visualized?
