SimScale is a computer-aided engineering (CAE) software product based on cloud computing. SimScale was developed by SimScale GmbH and allows Computational Fluid Dynamics, Finite Element Analysis and Thermal simulations. The backend of the platform uses open source codes:
The cloud-based platform of SimScale allows users to run more simulations, and in turn iterate more design changes, compared to traditional local computer-based systems.
SimScale GmbH was founded in 2012 by five graduates of TU Munich, David Heiny, Vincenz Dölle, Alexander Fischer, Johannes Probst, and Anatol Dammer with the goal of bringing CAE solutions to the mass market and provide an alternative to the traditional on-premises solutions which were the industry standard at the time. After a beta phase, the SimScale platform was launched in the second half of 2013.
On 2 December 2015, a community plan was announced making the platform accessible for free, as part of the initiative to democratize CAE and expand their user base of professional engineers and CAE experts to include small and medium scale enterprises, as well as students and individual product designers.
In 2016 SimScale began their collaboration with Autodesk by developing an add-in allowing all the Fusion 360 users to easily upload their 3D CAD models directly to the SimScale platform. Most recently, at the end of 2016 the SimScale Academy was launched, providing a new learning platform with on-demand courses on engineering simulation.
As of December 2016, the number of subscribed SimScale users reached 80 000, and the number of simulation projects freely available in the SimScale public project library surpassed 15 000.
The SimScale platform has several capabilities. Each capability with a suitable example for visualization is given below.
Finite element analysis moduleEdit
The FEA module of SimScale uses the open-source codes / solvers Code_Aster and CalculiX. These codes allow linear and nonlinear static/dynamic analysis of structures. Code_Aster is used simulations involving fatigue, damage, fracture, contact, geomaterials, porous media, multi-physics coupling and more. CalculiX has similar functionalities allowing users to build, calculate and post-process finite element models.
|Linear static analysis||Nonlinear static analysis||Linear dynamic analysis||Nonlinear dynamic analysis|
|Multibody dynamics||Harmonic analysis||Modal analysis (frequency)||Material Models|
Computational fluid dynamics moduleEdit
|Laminar flow||Turbulent flows||Incompressible flow||Compressible flow|
|Multiphase flow||Passive scalar transport||Fluid-Solid Body Interaction||Advanced modeling|
The Thermal module of SimScale uses OpenFOAM for solid-solid and fluid-solid thermal interaction problems. For thermo-structural analysis, SimScale uses Code_Aster and CalculiX. At present, SimScale allows uncoupled thermo-mechanical simulations, conjugate heat transfer and convective heat transfer analysis. Both steady-state and transient simulations are possible. In addition, fluid simulations also allow usage of Turbulence models. Types of analysis possible using SimScale include:
|Thermo-Structural analysis||Convection heat transfer||Conduction heat transfer||Radiation heat transfer|
Conjugate heat transfer (CHT), simulates the thermal energy transfer between a solid and a fluid, was added most recently to SimScale physics portfolio. It is most commonly used in the design of heat exchangers, heaters, coolers, electronic components and other heat sources.
|Conjugate heat transfer|
The other modules of SimScale include:
SimScale allows import of geometry in STEP, IGES, BREP, Rhinoceros 3D, Autodesk Inventor, SolidWorks, Parasolid, ACIS and STL formats; mesh in OpenFOAM, UNV, EGC, MED, CGNS formats. In addition, the geometry can be directly imported from their partner CAD platform, namely Onshape.
A SimScale add-in for Autodesk Fusion 360 has been released to allow direct import of models from Autodesk Fusion 360 to SimScale.
SimScale's CAE software finds application in a wide range of industries — such as HVAC, wind engineering, automotive, aerospace, electronics, industrial equipment and machinery, heat sinks, consumer products, biomechanics etc. Its use cases are very diverse. Japan-based Tokyowheel — a company that engineers technical carbon fiber racing wheels for competitive cyclists — used SimScale's CFD software component to determine the most aerodynamic wheel profile. QRC Technologies performed thermal simulations on SimScale to test multiple variations of their RF tester. Carlsson Autotechnik optimized the aerodynamics of their vehicle with the help SimScale's CFD module. Malaika, a company specialized in designing and producing car seats, employed SimScale's FEA simulation functionality to design safer car seats for children.
The SimScale Community Plan was announced on 2 December 2015 based on new investment round led by Union Square Ventures (USV). The Community Plan is free and includes 3000 computation hours and 500 GB of storage per year for any registered user. Simulations/Projects created by a user registered under the "Community plan" are accessible to all other users within the SimScale public project library. The SimScale public projects is a library of existing simulations/projects which any registered user can use as template to modify or copy.
SimScale outreach programEdit
SimScale has also organized several free webinars as a part of its outreach program to make simulation technologies more popular among hobbyists and designers. Webinars organized by SimScale include:
- CFD Master Class
- FEA Master Class
- Thermal Analysis Workshop
- 3D Printer Workshop
- F1 Aerodynamics Workshop
- Simulation in Biomedical Engineering Workshop
- CFD in Formula Student and Formula SAE Workshop
Additionally, in 2016 SimScale launched its Academic Program to foster relationships with schools, universities and individual researchers. Within the scope of the program SimScale offers students free subscription to the Professional Plan and sponsors student teams participating in competitions such as Formula SAE/Formula Student, SpaceX Hyperloop Pod Design etc.
