Finite Element Analysis

Please don't think me rude or snobbish. But, if you don't know the meaning of FEA, you are probably six months to a year of study away from being able to use it. It is way complicated. I use it, fairly successfully, and barely understand it.

What program are you using?

Finite Element Analysis (FEA) is a way to model more exactly how a solid will behave under certain conditions. It is basically the process of taking whatever component you want to observe and simplifying the calculations to minute fractions. It can be done for many things, airflow through a pipe, heat transfer, but one of the uses I have personal experience with is stress and strain on a solid model.

Basically instead of trying to calculate the stress on a component as a whole the component is broken down into very small polygons, usually triangles, each side of which is a line, the finite element. This makes it easier to calculate the forces, or stresses active on this very small straight line. And since the component is now made up of thousands or millions of these elements it becomes easier but very tedious to calculate the forces at each line. So FEA is almost always done by a computer in all but the most simple circumstances.

There is no trick I have ever heard of, ANSYS is an FEA I have used which allowed for customization of the polygon size and make up, and was relatively easy to use. But most 3D CAD software has a built in FEA program.

thank you very much

would you please send me ANSYS software
