안녕하세요, 여러분 ! Hello everyone !
Today is a busy day. Even busier than yesterday. But alhamdulillah everything is okay. Now, I will tell you a story about FEM (Finite Element Method) and the softwares.
Finite Element Method is one of numerical technique to solve an complex equation which (almost) impossible to solve it with analytical technique. It can used to solve structural analysis, Dynamic or Motion analysis, fluid flow, fluid-structure interaction, etc. There are many softwares which use FEM as their processes. But, the core is only 2. They are general purpose and specific purpose softwares.
General purpose softwares are softwares which can solve any application of FEM like structure stresses, car deforms, etc. Of course general purpose softwares are more expensive than specific purpose softwares because of their versatility. The examples of these softwares is ANSYS, NASTRAN, SAP, etc.
Specific purpose softwares are softwares which can solve only specific application or problem of FEM. Generally, we can build our own program with FORTRAN, Turbo Pascal, or Visual Basic to solve FEM problem. Because of their simple process, this softwares is cheaper than general purpose softwares.
Okay, this is my story about FEM and its softwares. Because tomorrow will be a busy day too. I must take a rest soon and prepare for tomorrow. See you everyone ! 안녕히계세요 !
