Heat transfer is the transfer of thermal energy in the form of heat from one system to another. For example, consider a pot of water being heated by an electric stovetop. Here, heat is transferred from the hot stovetop to the pot, from the pot to the water, and from both the heat pot and

Composites are made of two or more dissimilar materials which have different physical and chemical properties. These materials are combined to obtain the most desirable properties from the individual elements. The individual components within the finished composite remain separate and distinct, thus differentiating composites from solid alloys and mixtures. There are several types of composite

If you are somewhat familiar with CFD simulations, you will most likely have come across the term y+.  This dimensionless term is one of the most critical aspects of designing a mesh for your CFD simulation, particularly for wall bounded turbulent flows.  This can make or break your CFD solver’s ability to accurately predict the

When material is subjected to constant load over a prolonged period of time, its deformation gradually progresses leading to failure of the material. This phenomenon of material failure is called creep. The creep deformation will be permanent even if the stresses are below yielding point of the material. The effect of creep rapidly increases at

In a multi-body finite element analysis (FEA) simulation, various components of different shapes, sizes, and materials interact with one another. Some of these components may be idealized as rigid, meaning they are non-deformable under the action of applied forces and moments. This assumption simplifies the model of complex mechanical and physical systems, thereby increasing the

Tie constraints are a powerful and effective tool for connecting different regions in Abaqus FEA model, ensuring they perform as a single, bonded structure during the simulation. They work by allowing the surfaces to move together as a single entity irrespective of their mesh and material differences. These types of constraints are often used to

One of the most important steps in solving fluid flow problems using CFD is selecting and setting the correct boundary conditions that accurately represent what is happening in real-life. Boundary conditions provide information to the solver on the behavior of the fluid at openings and surfaces in the computational domain (or as the name suggests,
