how make external load, like traffic load or the like, thx

apply distributed load like syy, sxx etc.

1- go to "initial condition" panel
2 - select "apply boundary condition"
3- select stress->syy from keyword list
4- using mouse select nodes that you want to apply stress at (it should be boundary nodes)
5- type whatever value you want to apply in the editbox and press "Enter" or "Apply" button.
6 - now you should see arrows showing direction of applied distributed stress in the main window
