Spring on nodes

marco

Hello,

I am trying to model a concrete slab on elastic support (a foundation for an elavator). Is it possible to assign a vertical spring to all nodes of the model (to simulate the elasticity of the ground)?
Here attached a picture of the model.

Thanks,
Marco

Yes....Select all elements and choose Elastic Support under "Loads and Constraints" tree. Runs only with internal solver...I think.
Picture shows a plate loaded with a pressure of 1KPa (1000 N/m2) and an elastic support 1000 Pa/mm. Uniform vertical displacement 1 mm

Thanks Andrea. For linear elastic analysis is perfect, but is there an option for elastic support only in compression? Maybe using the non linear solver. In the next step I would consider the ground only in compression.

Thanks, Marco

You can try with CCX using "compression only material". Is thinked to simulate concrete.
See manual

With internal Mecway solver I don't know

Thanks, Andrea.
