SimScale Documentation

Welcome to the SimScale Documentation. These pages aim to provide detailed information about how to use the SimScale simulation platform.

SimScale is a browser-based, online engineering simulation platform that provides powerful modeling and simulation capabilities. With in-browser 3D visualization, scalable on-demand computing capacity, and a pay-per-use pricing model, the SimScale platform enables a new way of using simulation technology.

SimScale integrates a broad variety of simulation tools from structural mechanics, fluid dynamics, and thermodynamics. Both Finite Element as well as Finite Volume-based solvers are available. The SimScale team and our partners are constantly expanding the feature set of the platform with new analysis types and other features.

Listed below you can find the most important resources in this documentation.

Getting started with SimScale

If this is your first visit to the SimScale platform, we recommend you to take a quick tour to get to know the basics of the SimScale Community, Dashboard, and Workbench. Also, take a look at our tutorial section.

Platform Features

The SimScale simulation platform (“Workbench”) covers a multitude of functionality, ranging from CAD/domain preparation tools (pre-processing) over the simulation setup interface to the online post-processor, used to visualize the simulation results. Find detailed information on the feature set of each of those components in the sections listed below.

Cad Preparation (Pre-Processing)

Every simulation starts with the 3D CAD-model that should be simulated. There are a few requirements the geometry needs to fulfill in order to be compatible with SimScale as well as making sure that the simulation can be solved efficiently. Find out more about how to prepare your CAD model for simulation here:

Simulation Setup

Learn more about the simulation capabilities of SimScale. SimScale’s simulation capabilities span from Finite Element Analysis over Computational Fluid Dynamics to Thermal Analysis. This section provides information on the types of problems that can be simulated, as well as an explanation of the different models and solver types.

Post-Processing and Visualization

Post-processing refers to the visualization of simulation results. Depending on your simulation, the result files can exceed multiple gigabytes in size, making a powerful and reliable visualization environment essential. With the online post-processor, SimScale provides a state-of-the-art tool for visualizing simulation result data. Learn more about how to visualize your simulation results with SimScale and how to conclude design changes in the following section:

Validation Cases

Engineering simulation is a powerful tool in any stage of the design process. However, simulation results are only as relevant as they are accurate. At SimScale we continuously aim to improve the accuracy of all integrated solvers and analysis types. Comparing simulation results to real-world experimental data plays an important role in calibrating the simulation platform. Find out more about how SimScale validates simulation data by reviewing our validation cases in the following section:
