Hi,

I have just started using solidworks/cosmos for some FEA analysis but I can't figure out how to model 3 point bending. This sould be very simple but cosmos is the most backwards FEA software I've had to use.

The problem I am having is I can't apply a load to the centre of the beam, only across the surface due to the fact that meshing is the last thing it does. I tryed creating a near ridgid solid at the centre to apply forces to but this was too difficult to solve apparently.

Any help would be much appreshated.

You can create split lines along the surface you are trying to analyze to create a smaller more localized surface to apply a load to. Or you can apply a remote load at a specified location.
Why are you trying to analyze a 3 point bending test anyway? Are you just trying to use it learn Cosmos? Or to validate physical testing? Or what?

Its for validating composite modeling against physical testing.

Creating two surfaces seems to have worked, thank you
