How to model a beam on elastic foundation?
I am trying to model a simply-supported beam on elastic foundation, kind of like the figure below:
So far, I have not been able to properly model the elastic foundation. I know that Ansys has an "Elastic Support" feature for 2D and 3D structures [N/m³]. However, I need it to be applied along the beam, that is, at an edge [N/m²]. I can think of two possible solutions (which I could not successfully apply yet):
1) To model an elastic support at an edge, so that Ansys will automatically distribute the stiffness at nodes. This is the best option, as I would not need to manually adjust the stiffness factor according to the mesh density.
2) To define springs (or bushing joints), one by one, at each node. This solution is inconvenient, since it would require me to individually define hundreds of "Named Selections" and "Connections", and to adjust the stiffness factor for each connection.
That being said, my question is: is there any way to define an Elastic Support along an edge? If not, is there any way to efficiently define connections at a number of nodes (for example, using command lines or editing Ansys' data files)?
In case it helps, my Ansys file is below:
