I think I got weird results when bending a beam.
I have set the body force as force 3: -1000.
I fixed one end of the beam. And apply load to the other end: force 1: -2000.
I guess force 1,2,3 signifies force along x, y, z direction, right?
I anticipate the beam will bend not only along z-direction, but also along x-direction. But the final result only bends along z-direction. Could anyone please take a look at the vtu file? Thank you!

Hi
If you use a linear elasticity model I guess the displacement will only be to the direction of the force. You should use the geometrically nonlinear ElasticSolve.

Re: Weird results when bending a beam
There is movement in the X it is just much smaller than the Z. The body force is per volume of the body, and the boundary force is per area of the boundary. Therefore the Z force is many more magnitudes than the X force defined.

Hi Peter and Kevinarden,
I have been able to see the X movement in linear solver when I remove the body force along Z direction.
I also try the nonlinear solver, it works well. Thank you.
