Larger Solid Mechanics Simulations | SimScale Platform Update 05/2015

BlogAbout SimScaleLarger Solid Mechanics Simulations | SimScale Platform Update 05/2015

The SimScale platform has implemented lots of new features since the last update and now allows larges solid mechanics simulations. Find more details below or, even better, simply log in and test them for yourself! Happy simulating!

New Viewer Functionality

Depending on the simulation type you are setting up, the interaction with the CAD model or mesh is an important part of your work. This is especially true for viewer-intensive interactions, such as the setup of contact constraints. The scene tree now allows users to toggle the visibility of single parts or faces via a dedicated button. This speeds up certain picking processes significantly.

The scene tree on the right now allows toggling the visibility of CAD models or mesh entities.

Furthermore, the coordinate system icon in the lower left can now be used to align the 3D scene to one of the axis directions. Additional functionality for the viewer is already under development, so stay tuned!

New Boundary Condition Concept

The most powerful new feature is probably the way in which boundary condition types are now structured. From now on, there are boundary condition types available that define all physical quantities on a given face of the domain. In other words, where you earlier needed up to 20 single boundary conditions, you’ll now only need two or three to run your simulation. A practical example is illustrated in the image below. It shows a turbulent, incompressible flow simulation using a k-Omega-SST turbulence model that was created with just two boundary conditions.

The clustering of the new boundary condition type allows significantly faster simulation setups, especially for flow simulations.

Larger Solid Mechanics Simulations Possible

New numerical—as well as infrastructural features—now allow the setup of even larger finite element/solid mechanics simulations. Advanced time-stepping methods help to efficiently carry out dynamic and nonlinear solid mechanics simulation setups, while new memory allocation mechanisms ensure that very large meshes can be handled. As an example, take a look at this highly dynamic simulation of a valve train:

New Validation and Example Simulation Projects with the SimScale Platform

Each week, thousands of simulation jobs are carried out on the SimScale platform. Thousands of users in many different industry verticals analyze all sorts of products and applications. To accelerate their learning process and simulation setup time, our team has added yet another set of validation and example projects. You can simply import them via the Public Projects Library and get access to the complete simulation setup to derive your own analysis.
