🚀[FEA]: Support for one-dimensional linear elasticity.

[ahenkes1]

Is this a new feature, an improvement, or a change to existing functionality?

Improvement

How would you describe the priority of this feature request

Low (would be nice)

Please provide a clear description of problem you would like to solve.

Currently, only 2D and 3D are supported for linear elasticity. 1D would be very nice, especially for development and debugging as well as tutorials. I created a PR to add 1D support.
