FEA, THAT NEEDS TO UNDERSTAND...

 Hey Guys, Today we are discussing an important topic which is, How we can check our mesh? Is it right? according to the ideal shape? and how can I correct it if it is not? Firstly understand that this Quality check has two parts in which are Part I and Part II will be posted very soon.  So, now let's understand why quality checks? When we carry the meshing for a complex geometry our mesh is get distorted from its ideal shape. Every element is designed to work properly within a certain range of shapes of distortion. Exactly how much distortion it depends on is get known to us by the quality check of mesh.           The Ideal shape for a Triangular element is an Equilateral triangle and for that of quad elements, it is square. And for the tetrahedron element is a regular or isosceles tetrahedron and for Hexahydron it is a cube. When we assume the actual shape or ideal shape of our mesh and place it in the model, the shape may differ from its natura...

 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...
