Objectives
The purpose of the Computational Methods in Mechanical Engineering course is to provide the student with the ability to solve complex engineering problems with the help of the most recent software available. Besides acquiring theoretically knowledge about the finite element method the student acquires skills on the use of software and programming languages that allow him to solve practical problems. OCTAVE and ANSYS are both commercial software used in this course.
Subject matter
OCTAVE programming language applied to the matrix structural analysis. Introduction to the finite element method. Finite element method in beams. Static analysis, dynamic, instability and harmonic. OCTAVE applications involving structures composed with elements such as bars and beams. Introduction to finite element commercial software ANSYS. Comparison of results between OCTAVE and ANSYS. Introduction to the ANSYS programming language (APDL). Solution of plane elasticity problems by the finite element method. Applications in two-dimensional and three-dimensional with ANSYS.

Teaching method
Theoretical Lectures and laboratory sessions are included. At the lectures notes at the blackboard are given as well as powerpoint slideshows. A the Lab sessions the students interact with PC machines using the installed software (OCTAVE and ANSYS).
Evaluation method
The continuous evaluation finishes at the last day of classes in the semester and it consists of two projects and two mini-tests:
1st Project ( TR1 ) – Individual work.
2nd Project ( TR2 ) – Team work.
1st Test ( T1 ) – Individual and covering first part of the contents of the classes.
2nd Test ( T2 ) – Individual and covering second part of the contents of the classes.
All the projects and the test are mandatory and the attendance to the classes requested. The projects require the elaboration of reports. To be approved in the discipline, the student must have positive weighted average for the four classifications, computed by the following formula,
0,3 x TR1 + 0,2 x TR2 + 0,25 x T1 + 0,25 x T2 >= 10
In the case of failure in the previous evaluation it is possible performing an Exam (E) being the approvation dependent on (TR1 and TR2 can''t be repeated, it prevails the score obtained previously):
0,3 x TR1 + 0,2 x TR2 + 0,5 x E >= 10
The minimum for the Exam is 9,5val. The projects here correpond to the previous mandatory projects developed during the semester.
