Learning Strategies
This module involves development of competence in both theory and practical skills and a minimum level of attendance of 80% is a requirement.
Knowledge will be attained by the completion of a series of practical assignments completed inside and outside of delegated class hours. This will be supported by lectures, notes and relevant webinars.

Assessment Strategies
There will be 5 gradable practical assignments conducted during the semester. These assessments will come with a marking scheme from which practical competence will be assessed.
An assessment project integrating both the solid modeling and Finite Element Analysis strands of the module will make up one of the scheduled assignments.
