Material and section properties
Start to define the material properties – go into the properties module

Now create a section – this adds the beam cross sectional info.
Then apply this section the framework geometry.

We then orientate the bea
sections.
Select the beam sections t at you wish to orient and type in a refer nce direction (in this case 0,1,0) and the local direction of the beam is displayed.

We can render the beam s ctions to view them graphically. Go to View in the menu bar and select ‘Part isplay Options’. In the ‘Part Display Option’ window change the render type to haded and then check ‘Render Beam P ofiles’ and apply the new settings.

3.
Define the firs analysis step
Create a static general ste with the following settings. Nlgeom: On Initial Increment size: 0.1 Max Increment size: 0.1 The Nlgeom option update the geometry as the analysis progresses. This is generally used for Non-linear and large displacement analyses. The increment settings specify that the first time step attempts to solve 0.1/1 of the analysis rather than the entire analysis like the previous tutorial . It also specifies that there should be a minimum of 10 time steps in the sol tion and that no time step should be larger than 0.1/1.

Define restrai ts and loads
In the load module define t e loads and restraints Fix the 4 corner points at o e end of the box in all 6 degrees of free om. Add a 100N concentrated force v rtically to the model at each of the 4 cor ers on the opposite end.

5.
Meshing
Define a global mesh seed of 20mm.
Then hit the meshing icon to mesh the model.
After this operation the mo el should essentially look unchanged.

Open the results file and plot the results
Sets the deformation scale Sets the defor ation scale
Plots the stresses
Animates the image Try animating the image to see how the restraints hold the model in place whilst the force deforms the opposite end.
