Quality Checks (PART II)

-

 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 runs in the background. Like software, Simscale provides this also hyper mesh and other software.


3. Drag node:

The drag node is a feature in which we just drag the nodes and the advantage for this is that when we drag the nodes it instantly shows the effect of how it is going.


P.S.: There is a cation while using the auto meshing program. For 2D meshing jacobian/distortion improvement of 10 noded tetra meshing, sometimes software moves the nodes out of geometry by a considerable amount. This could cause visible kinks and distortion of geometry.

THANK YOU !!!

HAPPY LEARNING!!!😃😃😃

EFFECT OF BIASING IN MESH

 Hey guys, In a previous blog, We have talked about the effect of mesh density on critical areas. Today in this blog we are going to talk about the effect of biasing in mesh... I know this time this is pretty much late due to some issues I am unable to write. But now let's continue this ... Firstly let's talk about  What is Biasing in the mesh? The mesh Biasing means in meshing we are focusing on the particular or say critical region where we know that the stress can occur. So improving mesh density in that particular region is known as biasing. But now you will ask what is the difference between the Effect of mesh density on critical areas... It is the same explained in the previous blog... Actually, it is  not,  Although we are doing mesh refinement in that region. and also we are excluding some mesh refinement from the outer region of geometry where the stress concentration is low. Also, we can call biasing as it is the structured way of doing mesh. or We can call...

WHY STIFFNESS MATRIX IS IMPORTANT IN FEA

-
 Hey guys,  Let's talk about some important thing which is the stiffness matrix. The stiffness matrix is used in every type of analysis either it is static or dynamic. So what is the stiffness matrix as its word suggest the stiffness of an object or stiffness of anything  The stiffness matrix is a matrix which is the stiffness of any elements or the structure which is expressed in the matrix form for solving the governing equation of the problem to get the solution. The stiffness matrix is the key to the treasure to the FEA. Bcoz if there is no stiffness matrix associated with your problem then we cant solve the FEA problem. The stiffness matrix is denoted by this [k] . The matrix mainly depends on the properties which are the material and the geometric structure. For deriving the matrix for any geometry or shape of elements there are three types of methods which is... 1. Direct method: The  direct method is easy to understand but difficult to program so the commerc...

INERTIA RELIEF ANALYSIS

 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...
