I am mechanical engineer, my passion is the simulation in 3D/2D and uses of software that help to goal solutions. We Learn CAD, Calculator, Building, Design, Schedule task, etc. The area of mechanical engineering is wide, so we will find that not only with knowing the operation and experience can find the solution, but also with the use of FEA we can find solutions and even predict machine failure situations through mathematical models and simulate reality with the help of computational tools. Let us help each other find the way to the solution of many case studies in the field of design, manufacture, construction and operation of the large machines that surround us.
