FEA, THAT NEEDS TO UNDERSTAND...

 Hey guys, As related to the previous part we are going ahead with the quality check as we are discussing How to improve the quality of poor elements? For this, I have search too much and spend too much time but I found very few points. But these points really get into work for everyone. This blog post is going to be small but worth in knowledge, So let's take a look at which points are those. 1. Manual Adjustment: Let's talk about the oldest technique which is only there a few years ago which is. This method consists of manually translating the nodes in today's software we can't just manually translate the nodes we have to remesh it. So we can directly remesh the part where the mesh quality is poor. This method is time-consuming 2. Auto quality improvement program: As its name suggest that all work is done by the special programs. Just we have to give the body for the program, the program automatically meshes the body to improve the quality. A special software program ...

 Hey guys, Hope you are doing well, in today's topic we are going to discuss the shell meshing and its types and some important question that you will get after, we have talked about so many sections. So let's start with what is shell meshing? and how it works. shell meshing is nothing but simple meshing which includes 2-D mesh on the surface which is either quilt or on the mid surface or at the boundary. In this type of meshing, the software generates the 2-D mesh of quad or triangular elements, which has a low thickness value.  The shell elements consist of three methods: 1. Midsurface: This method generates the mesh at the mid surface of the geometry and this method is preferred for the thin-walled surface. 2. Shell:   Applies a triangular or quadrilateral shell mesh to quilt surfaces. 3. Boundary:  Directly apply the mesh to the surface of geometry and the interior of geometry has no mesh. Different type of elements for shell meshing: 1.Pure quad element 2.Mixed ...

  Hello Guys, In the previous one we have discussed mainly, the types of meshing in today's blog we will understand how to mesh and what should be done while meshing to improve the quality of the mesh and have an accurate result... so let's go There are various points that should one remember while carrying meshing which we are going to discuss... 1. Spend sufficient time studying geometry:  For carrying out the meshing in a good way we have to study geometry properly. Most of the time it is observed that most of the CAE engineers directly do to meshing job. That's the biggest mistake I have done in the past when I directly go with the meshing. Here is an imp step to understand the curvatures and other things of the geometry by which we can apply the options like proximity and curvature and also we can decide the element types by which. 2. Time: Nowadays it is very important to look at the clock. because it is very important according to the boss's and client's poin...

 Hey guys Today we are talking about the most important topic i.e. the nonlinearity of FEA.  What is non-lineaities? We have talked about linear and non-linear analysis. And how they differentiate from each other. Every problem that we encountered in real life is non-linear. But for the sake of simplifying the problem, we do it with the linear analysis.  What is the linear analysis means? In which for solving any type of problem we considered that the force and the displacement (As an output) are changing linearly. As in the linear analysis the stiffness of matrix doest change it remains constant.                As in the non-linear analysis, there are different types of non-linear analysis. The nonlinearities vary or it depends on various factors there are various types of non-linearites such as a 1) Material nonlinearity 2) Geometric nonlinearity 3) Contact nonlinearity   1) Material nonlinearity As in Material nonlinear...

 Hey guys, Today we are talking about the degrees of freedom which is dof''s. The dof is the freedom of any point that it wants to move in a particular direction. T he maximum number of logically independent values, which are values that have the  freedom  to vary. In the CAD or designing of any component, it is very important to understand about the dof. If we don't consider it may lead to failure. Also in FEA, the dof is very important in terms of calculating the result of getting the proper values from the mesh. The principle of meshing works on the dof. In which each node has its own dof. We will be going to talk about the mesh and why mesh is important and how it works later on in detail. But in short, the mesh is the important part in which it divides the modal into the element and nodes so that at each node we can extract the result from it. The nodes are points created by elements. Going back to the dof, each node has its own dof. We know that we have the 12 no of...

 Hey Guys,  Today we are talking about the Inertia of relief analysis. what is Inertia relief analysis? The inertia relief analysis is such a type of analysis in which the analysis of unconstrained bodies is done. So what is mean of unconstrained bodies, the bodies which have not any degrees of freedom fix or all dof's are free is known as unconstrained bodies. In real practises there are various unconstrained bodies are there. For doing such types of analysis we apply the fixed support or the remote displacement but in real conditions, they are not subjected to any of the constrained motion. So for evaluating these results we have to use the Inertia relief analysis           The procedure of Inertia Relief analysis is to balance externally applied forces so that bodies with no or partial boundary conditions remain in the equilibrium position.    Let us assume the case of an Aeroplane in cruise- When the aeroplane is on the ground we hav...
