ABAQUS

Abaqus FEA (formerly ABAQUS) is a software suite for finite element analysis and computer-aided engineering, originally released in 1978. The name and logo of this software are based on the abacus calculation tool. The Abaqus product suite consists of five core software products:

  • Abaqus/CAE, or "Complete Abaqus Environment" (a backronym with an obvious root in Computer-Aided Engineering). It is a software application used for both the modeling and analysis of mechanical components and assemblies (pre-processing) and visualizing the finite element analysis result. A subset of Abaqus/CAE including only the post-processing module can be launched independently in the Abaqus/Viewer product.
  • Abaqus/Standard, a general-purpose Finite-Element analyzer that employs implicit integration scheme (traditional).
  • Abaqus/Explicit, a special-purpose Finite-Element analyzer that employs explicit integration scheme to solve highly nonlinear systems with many complex contacts under transient loads.
  • Abaqus/CFD, a Computational Fluid Dynamics software application which provides advanced computational fluid dynamics capabilities with extensive support for preprocessing and postprocessing provided in Abaqus/CAE.
  • Abaqus/Electromagnetic, a Computational electromagnetics software application which solves advanced computational electromagnetic problems.

The Abaqus products use the open-source scripting language Python for scripting and customization. Abaqus/CAE uses the fox-toolkit for GUI development.

APPLICATIONS

Abaqus is used in the automotive, aerospace, and industrial products industries. The product is popular with academic and research institutions due to the wide material modeling capability, and the program's ability to be customized. Abaqus also provides a good collection of multiphysics capabilities, such as coupled acoustic-structural, piezoelectric, and structural-pore capabilities, making it attractive for production-level simulations where multiple fields need to be coupled.

Abaqus was initially designed to address non-linear physical behavior; as a result, the package has an extensive range of material models such as elastomeric (rubberlike) material capabilities.

ANSYS CFD

Fluid flow issues occur in all sectors of engineering and can range from simple laminar pipe flow to complex multi-phase phenomena involving turbulence, rotating components, conjugate heat transfer and chemical reactions.

As channel partners and specialist users for ANSYS CFD and Flownex, we have the flexibility to provide efficient fluid dynamics modelling solutions for all types and scale of equipment. This includes specialist strategies and software tools for Wind Microclimate Assessment and Thermal Management.

We supply the complete set of CFD tools from ANSYS, including the renowned FLUENT and CFX solvers, supported by standard and customised training programmes.

We also undertake a wide variety of computational fluid dynamics (CFD) consultancy and desktop study projects in most industries involving internal or external flows.

To help engineers who use any CFD system or are tasked to review simulations undertaken by consultants or peers, we regularly run a concise 1 day Introduction Course on basic theory and applications. This provides an invaluable overview on what is behind the ‘black box’ of CFD software, how to interpret results and guidance on best practice.

Ensuring CAD geometry and meshing is appropriate to achieve the desired accuracy and computational efficiency is a vital stage of the CFD simulation process. With ANSYS SpaceClaim, we can prepare clients’ geometry quickly or help them create ‘CFD-ready’ models for themselves. The tetrahedral, polyhedral and hexahedral meshing capabilities available within ANSYS Workbench are ideal to ensure optimum refinement of the fluid dynamics model is achieved.

Complementary to our other software and services for the Chemical & Process and Oil & Gas industries, we have significant experience in helping operators and equipment manufacturers upscale operations and increase throughput, efficiency & reliability through adoption of CFD.

Training course - ANSYS CFD with FLUENT The purpose with this course is to give an introduction to CFD analyses using ANSYS Fluent. The course will focus on main aspects, but it will also provide an insight to more advanced capabilities in Fluent. When the course is completed, the student should be able to create a basic geometry, mesh it, and then solve the flow field with ANSYS Fluent. The student should be able to choose appropriate models to describe the physics of the flow, such as the effects of turbulence, multi phase, and heat and mass transfer. Further, the student should be aware of typical model limitations often encountered in CFD. Post-processing of results will also be introduced.

ANSYS TRAINING PROGRAM

ANSYS is a general purpose software, used to simulate interactions of all disciplines of physics, structural, vibration, fluid dynamics, heat transfer and electromagnetic for engineers.

Ansys CFD allows engineers to test systems by simulating fluid flows in a virtual environment — for example, the fluid dynamics of ship hulls; gas turbine engines (including the compressors, combustion chamber, turbines and afterburners) aircraft aerodynamics; pumps, fans, HVAC systems, mixing vessels, hydrocyclones, vacuum cleaners, etc.

COURSE MODULES

The total duration of this training program is Eight Weeks include live projects. classes will conduct 5-6days in a week and 2hour class per day. 1 hour of theory class and 1 hour practical session.

CAESAR II

How do you include the effects of pulsations, slug loads, blast loads, water hammer/surge and the opening of relief valves in your stress analysis? By learning how to use the dynamic module within CAESAR II you will be able to effectively conduct these types of analysis.

By using the full capability of the CAESAR II dynamic module, the engineer will be provided with a more accurate overview of the stresses in their system compared to a quasi-steady study. Thereby it may be that the required number of modifications are reduced or unforeseen failures are identified.

Various solvers are present in the CAESAR II dynamic module, namely: Modal, Time History, Harmonic and Spectrum Analyses. Which to select, and the parameters to choose, depends on the load case being analysed.

At the end of this training course our aim is:

  • Increased awareness of the dynamic aspects of piping systems
  • Competent in using the Dynamic module of CAESAR II
  • Can apply the CAESAR II Dynamic module to solve potential dynamic problems
