What is skin depth ? The skin effect is the tendency for an alternating electric current (AC) to be dispersed throughout a conductor so that the current density is highest at the conductor’s surface and exponentially declines as the conductor is drilled deeper. Between the conductor’s outer surface and a depth known as the skin […]
In the field of engineering, the practise of using sophisticated graphical software to examine designs and find solutions to engineering issues is referred to as engineering simulation, which is also known as computer-aided engineering (CAE). Finite Element Analysis (FEA), also known as Computational Fluid Dynamics (CFD), Thermal Analysis, Multibody Dynamics, and Optimization are all components […]
Conditional statement in comsol is very usefull for modelling complicated simulations. The core of the function is if((x>lowerlimit)*(x<=upperlimit),valueiftrue,valueiffalse) the value if false is then a second if the statement of the same form, and so on. The “*” in the formula is equivalent to the AND statement. One way is to use conditional expressions. An […]

What exactly is “Convergence”? Convergence in COMSOL Multiphysics: Convergence is defined as the process of arriving at a solution that is very near to the precise answer within some error tolerance or other convergence condition that was previously set.

What are Ferroelectric Materials? Materials that demonstrate ferroelectricity are referred to as ferroelectric materials. Ferroelectricity refers to a material’s capacity to exhibit spontaneous electric polarisation, and it may be a useful property. By applying an external electric field in the opposite direction, it is possible to invert this polarisation. Interested to Learn Engineering modelling? Check […]
PDE equation-based simulation in COMSOL Multiphysics (comsol pde interface): An equation with two or more independent variables, an unknown function that depends on those variables, and partial derivatives of the unknown function with respect to the independent variables is known as a partial differential equation (or PDE for short). The largest derivative included determines the […]
The Finite Element Analysis (FEA) method was first presented to the scientific community by Turner et al. (1956). It is a powerful computational technique that can be used to approximate solutions to a wide variety of “real-world” engineering problems that involve complex domains that are subjected to general boundary conditions.
