Finite Element Analysis

Perform FEA simulations in your browser

SimScale is a 100% cloud-based simulation software that enables you to test, validate, and optimize your designs through Finite Element Analysis via a standard web browser.

The Finite Element Analysis (FEA) component of SimScale enables you to virtually test and predict the behavior of structures and hence solve complex structural engineering problems subjected to static and dynamic loading conditions. The powerful online simulation solution from SimScale uses scalable numerical methods that can calculate mathematical expressions otherwise very challenging due to complex loading, geometries or material properties. SimScale has adopted a pay-as-you-go policy providing you with high-performance computing (HPC) directly in the Cloud, to help you design better products faster and more cost-efficiently.

Static Analysis

The Finite Element Analysis software component of SimScale enables you to perform simulations of structures, including linear static and nonlinear quasi-static analysis. In a linear case with applied static load, the structural response can be determined in a single step. Also, all types of nonlinearities can be taken into account, including geometric, contact, and material nonlinearity. Applications include heavy machinery, industrial equipment, automotive and aircraft parts, pipes, and bridge design.

Dynamic Analysis

Our structural analysis component allows you to analyze the dynamic response of a structure subjected to time-dependent loads and displacements in order to model structural dynamic problems in a realistic way. Additionally,  the provided initial conditions in the dynamic analysis feature, support an analysis of impact loads and resulting structural degradation. Applications are diverse and range from automotive parts and sports equipment to earthquake effects on buildings and medical cases.

Modal Analysis

As another feature of the FEA component, modal analysis can help determine the eigenfrequencies (eigenvalues) and eigenmodes (mode shapes) of a structure due to free vibration. The results are important parameters to understand and model structures which are subject to dynamic loading conditions. Additionally, a harmonic analysis can show the peak response of a system under a load in a given range of frequencies applied in buildings, bridges, rotors, spring mounts or engines.

Multibody Dynamics and Contact Constraints

SimScale allows the import of CAD models and meshes with both individual parts and assemblies. Linear contact constraints, such as bonded and small sliding contacts, are supported. The cyclic and general symmetry boundary conditions allow simulating a symmetric model. Nonlinearity enables a realistic and holistic design simulation; for this, we offer nonlinear contact resolution using the Penalty and Augmented Lagrangian methods to impose large sliding friction and frictionless contact constraints.

Material Models

The solid mechanics tool offers various material models. Suitable for many engineering applications within the yield or failure limit, the linear elastic model is the default option. For advanced applications beyond yielding, it extends several inelastic material models enabling you to see the effects of plasticity, creep, and damping in a structure. It also facilitates modeling of large deformation behavior using hyperelastic material models — Neo-Hookean, Mooney-Rivlin, Arruda-Boyce, Signorini and more.

Christopher Quijano

I have used a lot of simulation packages over the past 25 years, including Nastran, Ansys, SolidWorks, and a whole host of others. I have been using SimScale for about nine months now and it has become my goto simulation tool. It allows me to run models larger than I have ever conceived on my own workstation.
