High order discretisation methods in CFD

Aarhus University
Wednesday 21. Marts 2018,  10.00 - 16.40

With the advent of super computers, we require higher and higher accuracy in the solution of many engineering problems. This has historically, in CFD, mainly been achieved by using a denser and denser grid in combination with a low order discretisation methods. However, to gain a much higher accuracy, for the same computer resources, we could increase the discretisation order while maintaining the grid density.

During the seminar, we will address the advantages of higher order discretisation methods. In addition, we will discuss mimetic or compatible discretisation methods, which are numerical schemes that largely mimic the continuous differential equation. Mimetic and high order discretisation schemes will be discussed individually and combined.

The meeting is in the new facilities in Navitas at the harbour only 800 m from the ferry terminal so it is easy to walk from the ferry (See map in the bottom of the page). The meeting is in auditorium 00.117 with entrance from 01.078 (first floor).

After the seminar we will have the general assembly of DANSIS in the same place. Please note that the general assembly will be in Danish.

Members of DANSIS can participate in the seminar free of charge. Non-members are also invited to participate at a fee of 400 DKK. Register for the meeting
