Finite Element Analysis

What we can offer

  • Our engineers use Finite Element Analysis in our product optimisation process. It can identify the cause of in-service failures of existing products and then be deployed to design and optimise viable solutions within the constraints of the existing geometry.
  • Again, whilst FEA can be used on all materials and equipment it is especially valuable whilst working with complex materials and geometries.
  • Not only do we provide finite element analysis using the world’s most advanced FEA software, but all of our team are qualified engineers with high levels of experience working in multiple high-performance sectors. Crucially, as a technology development and design engineering solutions company we work with our clients to optimise and deliver best-fit solutions.
  • Our aim is to maximise the performance of everything we design to ensure it is efficient, cost effective and within the required performance criteria.

How we use FEA

We have experience using ANSYS and MSC One FEA suites. We have selected ANSYS Mechanical Premium as our in-house platform, but can provide services using other packages if required.

ANSYS Mechanical Premium delivers powerful finite element modeling capabilities to help make real engineering decisions. Features include support for:

Linear dynamics
Finding natural vibration frequencies, responses to harmonic loads and understanding behaviour during transportation (random or PSD vibration) or events such as earthquakes (seismic response) gives you the ability to accurately predict how designs will work in dynamic environments. Including pre-loading adds more fidelity and means that self-weighted, bolted assemblies — or even squealing brakes — can be simulated.

Moving beyond linear, elastic materials, you can simulate the behavior of materials as they undergo plastic or even hyper-elastic deformation (materials like rubber and neoprene). Non-linear simulation also takes into account contact and large deflection of parts moving around relative to each other, either with or without friction.

Simulations with many moving parts can be challenging to simulate and understand. Being able to quickly account for complex joints and part interactions using rigid body dynamics enables you to make design decisions with confidence.

Thermal modeling
Simulating heat conduction, convection and radiation across assemblies enable you to predict the temperature of components, which can then be used to examine induced stresses and deformations. Mechanical Premium enables you to read in power losses or calculated temperatures from other analysis systems or files, which means that CFD or electromagnetic simulations can be a starting point for thermal analysis. It is also possible to account for fluid flow through pipes and heat generated from friction between parts. All of these capabilities give you more accurate simulations and better results.


MSC One gives us access to a number of analysis applications such as:

  • MSC Apex (geometry manipulation, mesher and linear solver).
  • MSC Patran (geometry manipulation, mesher and non-linear builder).
  • Nastran Solve 400 & 600 (non-linear solver).

Using these tools, we can complete rapid linear analysis using shell or solid meshing in Apex. If the application requires more complex modeling of non-linear behavior such as contact, large displacement, material plasticity or non-linear temperature response, we can build in Patran and run with Solve 400/600.

FEA and its benefits

  • Finite Element Analysis (FEA), is a computer simulation technique that allows any design, product or equipment to be analysed in great detail. This allows stress, vibration, heat transfer analysis, and many other physical analyses to be carried out.
  • These designs are constructed, refined, and optimized before the design is manufactured.
  • FEA can be used as a ‘standalone option’ or as a suite of analysis options, including computational fluid dynamics (CFD) that we use in developing and evaluating a product during the design process.
  • FEA is especially beneficial for more complex materials such as carbon fibre. In some sectors, FEA analysis can be a prerequisite to certification or validation.

Benefits include;

  • Increased accuracy.
  • Enhanced design and early evaluation of critical design parameters.
  • Virtual prototyping.
  • Fewer hardware prototypes which can be aligned to rapid prototyping.
  • Efficient and less expensive design cycle.
  • Increased productivity, and profit.
  • De-risked design process
  • A powerful and visual tool to help our client’s understanding
  • A report can be produced as part of a quality control and audit process
  • Maximise performance through material selection and positioning and cost efficiency
  • Reduced R&D and development costs
  • Certification or verification- The simulation data output is only as good as the input data. At PES we have the engineering experience, expertise and calibre to identify and potential anomalies. We will cross check and carry out calculations to ensure the data output is correct. FEA is a key tool in the design process, but not a ‘standalone’ solution.

Applications of FEA:

  • Stress Analysis- Stress, strain, failure points, fatigue, creep.
  • Thermal Analysis- Conduction, convection, radiation, conjugate heat transfer.
  • Vibration Analysis- Modal, harmonic, random, transient dynamic.
  • Seismic Analysis- Equivalent static, response spectrum, transient dynamics.
  • Impact & Crash Analysis- Equivalent static, short duration explicit simulation.
