TAILIEUCHUNG - Chapter 12: Finite element programming with MALTAB

Chapter 12: Finite element programming with MALTAB, selected topics in linear algebra with MATLAB, and a collection of finite element programs for: trusses (Chapter 2), general one-dimensional problems (Chapter 5), heat conduction in 2D (Chapter 8) and elasticity in 2D (Chapter 9). | Chapter 12 I. Finite Element Programming with MATLAB Chapter 12 includes a general introduction to MATLAB functions selected topics in linear algebra with MATLAB and a collection of finite element programs for trusses Chapter 2 general one-dimensional problems Chapter 5 heat conduction in 2D Chapter 8 and elasticity in 2D Chapter 9 . This Chapter is published electronic format only for several reasons 1. the data structure of the finite element program will be periodically updated to reflect emerging finite element technologies and MATLAB syntax changes 2. to allow the course instructors to use their own MALAB or other finite element codes. 3. to create a forum where students and instructors would exchange ideas and place alternative finite element program data structures. The forum is hosted at http Using MATLAB for FEM1 The MATLAB Windows Upon opening MATLAB you should see three windows the workspace window the command window and the command history window as shown in Figure . If you do not see these three windows or see more than three windows you can change the layout by clicking on the following menu selections View desktop layout default. 1 May not be covered in the class. Recommended as independent reading. The Command Window If you click in the command window a cursor will appear for you to type and enter various commands. The cursor is indicated by two greater than symbols . Entering Expressions After clicking in the command window you can enter commands you wish MATLAB to execute. Try entering the following 8 4. You will see that MATLAB will then return ans 12. Creating Variables Just as commands are entered in MATLAB variables are created as well. The general format for entering variables is variable expression. For example enter y 1 in the command window. MATLAB returns y 1. A variable y has been created and assigned a value of 1. This variable can be used instead of the number 1 in future .
