Meshing a fluid domain involves discretization of the domain into discrete cells. Various meshing techniques are used to discretize a complex model with good quality mesh, which enables the solver to solve the problem without convergence issues.

The 3DEXPERIENCE platform provides a lot of capabilities that help to mesh different fluid scenario domains, for example from simple to complex. There are certain best practices that the user needs to follow when handling fluid domain meshing. This document mainly focuses on these best practices. The SIMULIA Fluid Model Creation app is mainly used for fluid domain definition and domain mesh creation.

Target Audience: Simulation Analyst and Fluid Simulation Engineer.

Concepts associated with performing random vibration simulations are presented in terms of the random response procedure available within the Abaqus finite element simulation software. The paper begins with some general background information on the topic of random vibration. The equations that form the basis for a random response simulation are then presented in matrix notation. The concepts of “correlated” and “uncorrelated” random excitations are discussed and illustrated. The random response procedure is demonstrated by solving a series of simple beam problems. 

This Best Practices document is applicable for all releases from Abaqus 2018 to Abaqus 2023. 

Target Audience: Engineers and Analysts responsible for simulating noise and vibration in mechanical systems

Connections or joints are used to assemble various engineering structures. Engineers face challenges in conducting the finite element analysis of assemblies involving connections. The 3DEXPERIENCE Platform provides a wide range of connection tools that can be used to model complex real life scenarios. 

Connection tools are the advanced tools provided in the 3DEXPERIENCE platform that join two or more supports with a defined behavior to model/mimic the real life scenarios. This Best Practices document gives an overview of how the connection tools available in the 3DEXPERIENCE platform model the real-life scenario using the handler node, connector element, and connectors. 

Target Audience: Tech Support, Finite Element Analyst, Mechanical Engineers.

SIMULIA Simpack is a Multibody Simulation (MBS) software for dynamic analysis of mechanical systems. Multibody Simulation allows an analyst to study the kinematic behavior of a system or to identify forces acting between two components at a much lower computational cost than a Finite Element Analysis. 

Flexible Multibody Simulation is an elegant approach that combines the benefits of the traditional MBS approach with the high fidelity provided by the Finite Element method. 

This document provides an overview of model reduction techniques, preparation of FE model, types of couplings, substructure generation steps, quality check of FBI files, and the best solver settings suitable for Flexible Multibody Simulation. 

Target Audience: Analysts, Consultants and Tech Support.

This Best Practices document demonstrates the use of advanced Abaqus features authored by a Mechanical Analyst using the External Solve feature of the Physics Simulation app.

The Physics Simulation is exported as an Abaqus Input file and is updated interactively with additional Abaqus keywords using a simulation process authored in the simulation templates in the Process Composer app. The updated Abaqus Input file is executed using the Compute Orchestration Service. The results are imported back into the 3DEXPERIENCE Physics Results app for post-processing.

Target Audience: Design Engineers, Mechanical Analysts, CFD Analysts, Methods Developers, and so on.
