FEbeam 2D
Read full descriptionHide full description
this app is designed to solve a very simple 2D beam problems in mechanical and aerospace engineering fields. It illustrates a step by step process from user input data to computing results. Text book is included within this app for further reading about the finite element method for solving problem. this app also serves as an essential tool for distant learning. There are handy cross sectional of different geometry calculator included in this app. The finite element theory can be found in the embedded text books.
Simplex Optima
Read full descriptionHide full description
The general form of an optimization problem comprises a linear function of variables, also called "objective function" and a number of constraint inequalities. The app can facilitate a maximisation as well as minimisation problem bearing up to 7 variables and up to 6 contraint inequalities. The solution algorithm is implemented by constructing and manipulating the Simplex tableau before calculating the parameters for which the maximum value of the objective function is obtained.
