SimScale Update 04/2016: Elastic Support and Improved Community Support
Commited to ensuring the best experience with SimScale for our users, we are constantly improving the platform and adding new simulation features. Here are the latest updates:
With the latest SimScale updates we enabled Elastic Support, a constraint boundary condition that allows you to add an elastic foundation to a part of your model without the need to add a domain representation like a spring or an elastic material layer to your setup. It is defined by a stiffness parameter and reacts to tension and compression.
The application above shows the stress analysis of a pneumatic actuator consisting of a piston, a spring and an elastomer diaphragm.
The results are shown both for an analysis involving the complete assembly as well as a second setup where the spring has been replaced by an elastic support boundary condition with the corresponding stiffness.
Using the elastic support, the mesh size and computation time have been considerably reduced as the spring does not need to be meshed and the cyclic symmetry of the remaining assembly allows one to investigate a subset of the model. You can find the public project here.

The elastic support can also be used to suppress undesired rigid body motions especially in nonlinear static analyses where inertia effects are disregarded and under-constrained systems are likely to diverge. This can be easily accomplished by adding virtual soft springs to the setup via elastic support.
For soft stiffness parameters, the influence on the results can be often neglected. The picture below shows a metal stamping process. Here is the public project.
