ABAQUS
An explosion is a rapid and violent release of energy, usually accompanied by a loud noise, heat, and pressure waves. Explosions can be caused by a variety of factors such as chemical reactions, combustion, nuclear reactions, or mechanical failure. Explosions can cause severe damage to buildings, infrastructure, and human life. To minimize the impact of such incidents, accurate and reliable simulation of explosions is crucial. Explosion simulation involves modeling the complex interactions of blast waves, shock waves, and debris with the surrounding environment. By simulating explosions, engineers and scientists can identify potential risks and develop effective safety measures. In this package, you will learn how to model explosions in different situations with practical examples, such as Air blast explosion simulation inside an RC room and Subsurface explosion simulation on buried steel pipelines.
9 Practical Workshops for SPH in Abaqus💡 | Abaqus SPH Tutorial
Smoothed Particle Hydrodynamics Tutorial: Abaqus SPH (Smoothed Particle Hydrodynamics) is a numerical method used in this software to model fluid-structure interaction problems. SPH in Abaqus is a meshless approach that uses a set of particles to discretize the fluid domain. The Abaqus SPH modeling tutorial is particularly useful for problems with large deformations, fragmentation, and free surface effects.

Earthquake simulation in Abaqus
It is known that an earthquake is a disastrous event that can cause great damage to buildings, structures, and even people. So it's essential to know how a structure will behave when subjected to an earthquake. Therefore engineers must take into account the possibility of an earthquake when designing a structure. With finite element analyses, engineers can predict the behaviour of structures under earthquake loading. With this method, they can determine the best way to design a structure to withstand an earthquake. In this package, you can learn how to do earthquake simulation in Abaqus to have the best design for your structure to save human lives. Three practical examples are presented to you to start simulating earthquakes: “simulating an earthquake over a gravity dam in contact with water and soil”, “simulating an earthquake load over a water-filled tank”, “Abaqus-Micro model simulation of seismic load over masonry wall (concrete brick)”.
Fluid-Structure Interaction also known as FSI is a multiphysics problem where the fluid and structure are coupled. The fluid flow can cause the structure to deform, and the deformation of the structure can affect the flow. So when you want to design something, you need to know how the structure will deform and how that deformation affects the flow. Common examples of FSI analysis are airplanes, cars, spacecrafts, and buildings. Other examples like junctions in piping systems, or the human circulatory system. CFD is a branch of research that uses numerical methods to solve the mathematical equations governing fluid flow, heat transfer, mass transfer, chemical reactions, and related phenomena. In Abaqus, you can model both methods. In this package, we present to you three workshops to get you started with Abaqus CFD and FSI: “Using Abaqus CFD methods, examining heat mixing and reverse flow characteristics in a T-junction”, “impact of air velocity over the short column”, “simulate fluid structure interaction on an aluminum body with a flexible tail in Abaqus”.
