Bio-Mechanical Abaqus simulation | Practical Examples
This package offers multiple practical examples on biomechanical simulations using Abaqus, covering a range of applications from dental to orthopedic and cardiovascular analyses. The workshops delve into finite element method (FEM) simulations, exploring static loading on human teeth, crack growth in bones under bending, bone drilling, and the behavior of titanium foam implants. Each tutorial emphasizes the importance of precise modeling and meshing techniques, utilizing dynamic explicit procedures, Johnson-Cook material models, and various contact and boundary conditions to simulate realistic biomechanical behaviors. Additionally, the package includes fluid-structure interaction (FSI) simulations for blood flow within coronary vessels, addressing both Newtonian and non-Newtonian models, and demonstrates the integration of computational fluid dynamics (CFD) with structural analysis for enhanced accuracy. For more details on this topic, including explanatory videos covering the necessary formulation and theory in the form of a course, you can check out our full package on Abaqus Bio-mechanical simulation. The introduced package includes all the workshops within this package, along with several lessons in video format, to help you master the theory of biomedical simulation in Abaqus.
Airfoil simulation with different angles of Attack | Ansys fluent
Airfoils are a vital and important part of many industrial units. For example, in many kinds of rotary equipment such as gas turbines and wind turbines or compressors, airfoils play a vital role. Another usage of airfoils is in the aviation industry, which they used in airplane wings. The crucial parameters that are important in airfoils are the drag and lift forces or drag and lift coefficients. By using these parameters, we can design better airfoils to achieve greater lift coefficients and lesser drag coefficients. With this package, you learn airfoil simulation; how to design, mesh, and simulate an airfoil. Also, you learn how to link MATLAB to Ansys Fluent to change the geometrical constraints and boundary conditions automatically (airfoil simulation Ansys). You can use this method for your own optimization.
Mixing tank simulation with Ansys fluent(2D and 3D)
The mixing process is crucial and highly effective in various industrial applications. It finds application in industries such as food and cement manufacturing, among others. This course focuses on the implementation of mixing processes in both 2D and 3D spaces.
This course begins with designing the geometry with complete details. Next, we learn how to use Ansys Meshing software to mesh the geometry in detail and assess the mesh quality. Following this, we apply appropriate two-phase and turbulence models to simulate the process, allowing us to analyze the results. Additionally, we create animations of the process to visualize how the mixing process occurs.
FSI analysis in Abaqus
Fluid-Structure Interaction (FSI) refers to the interaction between a deformable or movable structure and an internal or surrounding fluid flow. FSI simulations are vital for understanding and predicting the behavior of systems where fluid and solid components interact. These simulations enable engineers and researchers to study the effects of fluid forces on structures and vice versa.
FSI simulations are crucial in various fields, including aerospace, civil engineering, biomechanics, and automotive industries. They provide valuable insights into the performance, safety, and reliability of engineering systems. By accurately modeling the complex interactions between fluids and structures, FSI simulations can identify potential issues such as vibrations, instabilities, and structural failures.
In this package, you’ll learn simulating FSI in Abaqus within 3 workshops.
Blood Flow Analysis in Abaqus
Human blood is a vital fluid that circulates through the body, carrying oxygen, nutrients, hormones, and immune cells. Simulation of human blood is crucial for understanding cardiovascular diseases, hemodynamics, and therapeutic interventions. It enables researchers to study the complex behavior of blood flow, investigate disease mechanisms, and develop improved diagnostic and treatment strategies. This package contains three workshops that would help you simulate blood flow in vessels: “Human blood with coronary vessel Fluid Structure Interaction simulation in Abaqus”, “Blood and vessel FSI simulation using Abaqus-Co Simulation process”, and “Non-Newtonian blood flow Simulation in Abaqus”.
Script to transfer load from CFD to structural model in Abaqus
FEA offers various loading types, such as force, pressure, and temperature, which can be applied to different parts of an object, such as points, surfaces, edges, nodes, and elements. Therefore, applying accurate loading conditions on these features is necessary for reliable simulation results and the safe design of structures. Sometimes, the loading conditions are obtained by another analysis, such as CFD, and need to be transferred and applied to the structural model for the structural analysis; during this transfer, the loads might not be appropriately applied to the model, especially when the loads are complicated like the pressure profile of a space rocket. So in this package, a Python script is presented to solve this issue and transfer the loads properly to the structural model.
Water Simulation in Abaqus
Water is the primary component of the Earth's hydrosphere and the fluids of all known living things. Therefore, we build dams to store the water and transfer it through piping systems to use it for daily activities and produce energy. In industries, we use it as a cooler, solvent, hydroforming, cutting, etc. In this package, there are nine practical examples, such as the ones mentioned to teach you how to simulate water in Abaqus. These examples are explosions in the depth of the water, gravity dam simulation subjected to the underwater explosion, ball impact to the water, water jet cutting, etc.
Abaqus CFD Analysis
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”.
