Enhance your technical knowledge by registering for a half day seminar on Thursday, September 25th. Cost to attend is €140,-.
Co-Simulation regarding multiphysics simulations play an integral and indispensible part of today’s engineering workflows in designing advanced products. The simulation methods have evolved to a point where fewer approximations are made and more realistic predictions of coupled physics phenomena are obtained. This course will introduce the co-simulation engine (CSE), a general capability to couple multiple solvers to concurrently simulate the behavior of coupled systems. These solvers can range from Abaqus/Standard, Abaqus/Explicit, Abaqus/CFD, several partner’s products, and finally your own in-house codes. This powerful functionality is illustrated through examples spanning fluid-structure interaction, electromagnetic-structure interaction, and logical-physical coupling. We will finish with an example on how to use the CSE API to couple your in-house codes with Abaqus.
This seminar is a convenient chance for all simulation engineers to gain exposure to the value of fatigue simulation as part of everyday FEA practice. The seminar provides an introduction to modern methods of fatigue analysis with particular reference to fatigue analysis of FE models, particularly with Abaqus. Modern fatigue analysis methods for finite element models are reviewed with examples highlighting why modern approaches are necessary. Techniques such as strain-based methods to calculate life to crack initiation, modeling elastic-plastic stresses and strains from an elastic FEA model, and critical plane searching to determine crack orientation are covered in detail. Interaction between small and larger load cycles, critical distance methods, multi-axial fatigue, and the limitations of traditional methods are also covered. Special coverage is given to the application of critical distance methods to complex geometrical problems such as three-dimensional notches under biaxial stress cycles, fatigue analysis of threaded joints, fretting fatigue, thermo-mechanical fatigue, and creep-fatigue interactions. Specific issues related to fatigue lifecycle simulation are discussed including the simulation of physical fatigue tests and the types of problems that can be addressed using fatigue analysis with FE models. The modules within the fe-safe product suite are reviewed for application to fatigue of welded joints and fatigue of elastomers. fe-safe is technically advanced fatigue analysis software for FEA models. fe-safe incorporates the most sophisticated fatigue analysis technology available in commercial software. As a result, fe-safe is changing the way design engineers perceive fatigue analysis software tools.
This half day seminar will survey the design exploration and optimization packages offered by SIMULIA. First, we will review the techniques available in the SIMULIA Isight product family such as DOE, Approximations and Optimization that can be applied to any integrated application and mathematical model simulation workflow. Isight techniques enable multi-disciplinary and objective design space exploration for earlier phases of design, while the design is still parametric. In the second part, we will discuss in detail the more specialized non-parametric methods for structural and fluid optimization available in the SIMULIA Tosca product family. These methods interact with industry standard FEA or CFD packages and can efficiently handle a very large number of design variables. They can be very powerful for generating new concepts early in the design cycle or for fine tuning later when the design is mature. Used throughout the design process, both Isight and Tosca can lead to significant cost savings, product performance gains, innovative product design and a shortening of the design cycle in general.
