FEA, THAT NEEDS TO UNDERSTAND...

 Hey guys, I know this is too late but today we are going to discuss how we did not mesh to our FEA geometry to get successful results. So without wasting time let's get into it. 1) Back-to-back triangle should be avoided. Two tria elements should not be connected to each other directly. You can see this in this image. 2) On the plane surface triangular elements should be avoided. The recommended mesh is shown in the figure. 3) No mesh transition on the constant radius fillets/curvatures. Mesh transition should be carried out on the plane surface. As you can see in the figure this should not be recommended. 4) Avoid tri element on the outer edges and holes. It can cause the wrong results. 5) Some useful and recommended points that are not respectable at the professional level. This is shown in the following figure. 6) Circular hole should be molded carefully with a washer it means fine meshing at the circle. And minimum 2 layers around the hole. 7) Holes should be molded with an ev...

 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...

  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...
