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, We are going to dive a little more into the meshing. Bcoz this is a very important topic that needs to discuss with. When we are doing mesh on geometry. There are various types of bodies on them we need to do the mesh. In which it is having some critical areas where there is more stress concentration occurs. So we need some dense type of mesh over there.  Firstly let's talk about what is mesh density? It is nothing but the number of elements per unit area. As we know, if the density of mesh increases the computation time will go high.  So, here as we have discussed the meshing elements we know that the quad element has better accuracy than tria so here I have found this image in which it has the increasing elements on the same geometry. So, here you can see that as the number of elements increases near the hole. So now what we are getting through this. The geometry has a dimension of 1000*1000mm and a thickness of 10mm. We are going to pull it from the right side wit...
