PhD-defence: Computational methods for wave-structure interaction: numerical analysis of a RBF-based method
PhD defense by Morten Eggert Nielsen organized by Department of the Built Environment, Aalborg University.
09.11.2020 kl. 13.00 - 17.00
How to participate
Due to the Covid-19 situation, the PhD defence will be carried out via Zoom. Please send an email to Linda Vabbersgaard Andersen no later than 6 November 2020 and you will get an invite for the event and, if requested, a copy of the thesis.
Summary of the thesis
The thesis explores a new computational method suitable for simulation of non-linear ocean waves and their interaction with offshore structures. The new method is based on radial basis function-generated finite differences (RBF-FD), which provide geometric flexibility and high-order accuracy. However, the geometric flexibility comes at the cost of poor temporal stability, due to the mesh-free nature of RBF-FD. In order to improve the temporal stability, a new stabilization technique has been developed, and in combination with a new node generation and update strategy, the potential of the new computational method has been demonstrated.

13:00: Welcome by Moderator.
13:05: Lecture and presentation by Ph.D. student (45 min).
During the break, participants can email questions to the moderator, Martin Dalgaard Ulriksen email@example.com. If such are received, the questioner puts them forward after the assessment committee has finalized their question and answer round.
14:00: The assessment committee is asking questions to the work
16:00: End of defence. The assessment committee enters another “room”, evaluates and writes the final assessment.
16:45 (approx.): The assessment committee rejoins the “Defence room” and announces its decision.
17:00: End of event.
