Fem help needed plz

[extrasolar]

Hello all


I need your Help please.
I'm trying to load test a support beam for my cottage.
I am Using UG NX 3

My problem is that I can't get the 2D mesh to see my load values and my constraints values. I can't seem to be able to link them my guess is that i am missing a step.

my steps

1) Draw the beam as a solid
2) enter into structures
set the solver to NX nastran
analysis type Structural
Sestatic Multi Constraint

3) I create a mid surface along the beam.
4) place the 2D mesh along the mid surface (overall element size 0.250
5) Then I create hard points for my load and two constraints.
6) Apply my load value in in the mid of the beam at the midpoint.
7) Apply my two constraints in the middle of the beams (W) 2 Inch's from either end.
8) using attribute editor I set the mesh to use the material type I want and set the thickness I want

9) test the beam
I get the following errors
Force 1 "has no underlying mesh and will be ignored in the analysis" "suggestion create a mesh that uses the same geometry as the load"
I get the same error for the constraints.

if someone can show me the correct steps to linking the mesh to the load and constraints the would be a huge help
thank you.
