In our example, we will use the QuickStart feature of the program and there is no need to define the Material manually. You can go directly to Step 4. Draw the Model on screen.
If on the other hand, you prefer to define the Material manually, then you can follow the instructions on this page.
Click 
to define Material(s). For details, see Materials.
You need to define the Material Name (optional), Material Density d (optional in general, only needed if you are to define self-weight loads, which is not the case here) and Material Elastic Modulus E for each Material. Use the following properties:
•Name: Steel S 235
•Elastic Modulus E = 210 GPa
•Density d = 7850 kg/m3
•Yield Stress fy = 235 MPa
Then Click the "Add new" button. The new Material will be added to the table that shows the Model Materials.
Then Click OK to exit the Materials form.
