FEM/FEA simulation and analysis
The Finite Element Method (FEM) is a numerical method for the approximate solution of partial differential equations as well as the solution of integral equations. The practical application of finite element is commonly referred to as finite element analysis (FEA). The basis of this simulation method is the complete elimination of differential equations or their simplification to ordinary differential equations, which are solved by numerical methods such as Euler. In fact, in the finite element method, the object or set in question is divided into very small elements and the corresponding equations for each element are solved. It should be noted that the accuracy of finite element analysis is strongly dependent on the quality of modeling, consideration of boundary conditions and the allocation of the correct material, as well as proper meshing of the model.
Finite element analysis and simulation is used to study the static and dynamic loading of mechanical equipment and structures.
By stress simulation and analysis, the critical points of a structure or equipment can be identified and the Factor of Safety - FOS can be calculated in the part or chassis.
CFD,FDS and Pyrosim simulation
Fluid mechanics is one of the most important disciplines in the mechanics of continuous environments. Fluid mechanics begins with the same principles as for solid mechanics, but what ultimately distinguishes the two is that fluids (gases and liquids), unlike solids, cannot withstand shear stress. Knowing this, equations have been devised to analyze and simulate the motion of fluids. These equations are called Navier – Stokes equations in honor of Navier and Stokes by two British and French mathematicians. Analysis and simulations of CFDs, Computational Fluid Dynamics, are in fact solutions to the Navier-Stokes equation for small volumes of the original model. In this method, the whole simulation criterion is first divided into very small volumes in the meshing operation and after applying the boundary conditions, the mentioned equations are solved for all elements.
Fluid simulations or CFD simulations are generally similar to FEM static and dynamic analyzes. In both methods, much smaller elements are used to solve than the original model.
Today, with the increasing speed of computer processing, simulation and CFD simulation have found a special place in the design of new parts and devices and fault analysis. Important points that can be calculated in fluid analysis and simulation and heat transfer are:
Prepare diagrams of velocity, temperature and pressure of fluid (gas and liquid) at any point of the three-dimensional model
Preparation of plot and counter speed, temperature and pressure of fluid (gas and liquid) in internal and external surfaces
Create a fluid flow path diagram (gas and liquid)
Plots and diagrams of heat transfer at external and boundary levels
Calculations of speed, temperature and pressure at different levels and volumes
Free surface modeling in liquid
Modeling and simulation of how smoke is distributed
