Advised by: Dr. Kushan Wijesundara and [Sameera Hippola)

Project summary

• Civil engineering structure modelling
  • Elementwise local stiffness matrix calculation generation.
  • Structure’s global stiffnexx matrix calculation.
  • Load matrix generation.
• Lieanr system oprations.
  • Linear system representation : dense and sparse
  • Linear system solving: Gauss ellimination on dense and sparse matrices, iterative numerical techniques.
• Backtracking to translate the linear system solution to civil engineering structure.

The main objective of this project was to find the time and memroy efficient way of computing the results.

Please note

This work was done as a partial requirement for CO328 Software Engineering) course. **This implementation consists of the linear and non linear region analysis **
