The main goal of this course is to provide the student with the fundamental tools for feeling comfortable when dealing with the different aspects of simulations based on the Finite Element Method (FEM), applied to structural analysis (FEA).
The course is mainly focused for Naval Architects, but the FEA aspects which it contains makes it very advisable also for any Engineers and Professionals dealing with structural analyses, and for Engineering students and PhDs willing to get familiar with FEA procedures.
The course has 11 chapters of on-line training, each of them containing a short theory section and apractical exercise. After each training chapter, the students have one week to solve and deliver the practical exercise. The total time of the course is 50 hours.
