· Introduction: Overview of theapplications of Computational Mechanics in Oil & Gas and OffshoreEngineering. Necessity and outline of the selected course topics.
· Problems ofComputational Mechanics: Problems ofstructural, thermal and fluid flow analysis. Differential equations in 1D, 2Dand 3D spaces.
· Theory andfundamentals of the Finite Element Method: Decompose the computational mechanics problem in “small” (finite) 1D, 2Dor 3D elements. Use of low order Taylorapproximation for the solution in each element. Introduce nodal interpolationand the nodal values as unknowns. Satisfy the differential equation within thefinite element using the Galerkin-Ritz methodology, thus transforming the unknown functions in discrete unknown nodal values and the differentialequation in algebraic equations. The Finite Volume Method as a zero-orderfinite element method. Matrix formulation. Today’s available Software.
· Finite Elements inComputational Mechanics Problems: Nodalvariables matrices, load vectors and displacements hypotheses for bars, beams,plane elements, plates and shells, nodal variables matrices and load vectorsfor Laplace and Poisson equations. Demonstration using commercial Software.
· Mesh generation: Approximation of the global solution through an appropriate mesh offinite elements. Convergence aspects and self adaptive meshing with use ofcommercial mesh generating software. Structure and unstructured grids Delaunayor advancing-front methods, Constrained Delaunay Triangulation,Mixed-Element/Hybrid Grids. Demonstration using commercial Software.
· Application ondifferent examples: Application of thefinite element analysis on specific structural, heat and flow problems.Demonstration using commercial Software.
· Computer laboratory work: Individual orsmall group studies where students can apply their gained knowledge oncommercial FE-software (ANSYS/SAP) and evaluate practical problems for better comprehension.

|Planned learning activities and teaching methods||
The taught part of course is delivered to the students by means oflectures, conducted with the help of computer presentations. Lecture notes andpresentations are available through the web for students to use in combinationwith the textbooks. Furthermore theoretical principles are explained by meansof specific examples and solution of specific problems.
Lectures are supplemented with computer laboratory work carried out withthe supervision of a lab assistant. Here a demonstration of actual problems andcomputational methods takes place. Additionally, during laboratory sessions,students apply their gained knowledge and identify the principles taught in thelecture sessions by means of working on different modelling tasks andevaluating simulation results.
