FEA Finite Element Analysis

The Finite Element Method (FEM) is at the core of most predictive work at AAL. Best in class software is available to cover a broad spectrum of applications and client's needs and vision. The main simulation suite at AAL is SIMULIA with ABAQUS (Standard & Explicit solvers) and its complementary tools: FE-Safe (fatigue), Tosca (optimisation).

Exhaust manifold, thermal FEA Additionally, ALTAIR's HyperWorks suite is employed for linear analysis with OptiStruct (Nastran), MotionSolve (Multi-body dynamics), AcuSolve (CFD) and HyperMesh / HyperView.
Other tools are available for specific applications: Matlab (science mathematical tool), Coustix & AlphaCell (NVH and acoustics), Python programming and ABAQUS plug-ins. Exhaust manifold, thermal FEA


NVH Noise Vibration & Harshness

Noise radiation from engine The prediction of noise, vibration induced fatigue, sound quality and general acoustics has been a speciality at AAL from the start of the company. The combination of tools such as ABAQUS, OptiStruct (Nastran), Fe-Safe (fatigue), Coustix (Boundary Element Method) and AlphaCell (design of sound packages) enable the solution of linear and complex non-linear NVH problems. Furthermore, results are presented in a variety of formats to suit client's needs, allowing for easy comparison to test results. Advanced post-processing can be implemented via Matlab, music production tools or Python. Silencer Sound Transmission Loss

Some examples include: engine / transmission noise radiation, powertrain covers noise optimisation, study of mounting isolation, full vehicle noise at driver's ear, intake / exhaust systems, shock wave events on large assemblies (noise, stress & fatigue), sound quality on domestic appliances, speaker optimisation, hearing aids ... Contact us for a full list, we can provide advice on small (one day) jobs to large development programs.


CFD Computer Fluid Dynamics

CFD engine water cooling AcuSolve is the main CFD tool at AAL. It offers fast, robust and accurate fluid simulation capabilities. Amongst the main powerful features are: flow and heat transfer, several turbulence models, fluid-structure interaction and moving mesh technology. CFD engine water jacket flow

Typical applications are: engine coolant studies, optimisation of coolant jacket flows and gasket hole design, generation of thermal boundary conditions for FEA, under-hood flow, vehicle wind tunnel, calculation of wind loads on rotating parts such as radar systems, etc.


Optimisation Organic Designs

CFD engine water cooling TOSCA for ABAQUS allows for design optimisations from concept stage, generating organic shapes based on FEA calculations. It helps to inject early simulation results into the development process to guide designers from the start of a project, while meeting performance targets and keeping material weight and cost to a minimum. TOSCA frame optimisation

Furthermore, this non-parametric approach reveals unusual organic designs that allow for the implementation of innovative shapes on the final product. CAD is also produced via intelligent smoothing algorithms to arrive at a usable geometry for further drafting.


Software Development Tailor-made Tools

Design and generation of advanced tailor-made calculation environments. We develop tools from small plug-ins to complete software packages for detailed calculations.

Some examples comprise the development and deployment of a comprehensive engine loads calculation suite ('ENGLOAD'), utility plug-ins for ABAQUS pre- & post-processing, and a bore distortion tool in Python to automate post-processing of FEA results.
