I am trying to create a dummy study that will show me what is the deformation of a tube when force is applied on the midle of it so i:
1- Created/Sketched a round tube of 20in (2 circles - and extruded boss, very simple) OK
2- Created a static study and applied fixtures on the tube ends. OK
3- Clicked External Loads -> Force. OK
4- Clicked the tube selecting Face1 that is the entire tube. OK
5- Selected nonuniform distribution - OK
6-> Now it says i have to select the coordinate system but i have no idea on how to do it????
It is showing the X,Y,Z arrows on the left bottom corner of the window.
I tried to select "Origin" from the menu tree with no success.
How to select it?
