GMGW-2 Overview

GMGW-2 will consist of the following events.

Agenda, Participants, and Registrants

See the main GMGW-2 Agenda page for details on dates and times, participants, and attendees.


Presentations are listed according to their order in the Agenda. All files are PDFs.

Case 3 - OPAM-1 Parametric Remeshing

Case 1 - Exascale Meshing

Case 2 - GMGW-1 HL-CRM Remeshing

Mini-Symposium: Mesh Effects on CFD Flow Solutions

Register with AIAA

You must register for GMGW-2 with AIAA. Workshop registration and payment is handled through their SciTech website (scitech.aiaa.org/Register).

THERE IS ONE EXCEPTION. If you will only attend the Mesh Effects on CFD Flow Solutions mini-symposium on Sunday afternoon, you do not need to register for GMGW-2 with AIAA or pay. We do ask that you notify us by email at meshingworkshop@gmail.com so that we can maintain an accurate headcount for planning purposes.

Presentation Template

Participant presentations are currently limited to 15 minutes in order to fit all the material into the workshop's two days.

The presentation template from GMGW-1 has been modified slightly for GMGW-2. It will be most appropriate for Case 2 (Remeshing) as that case mirrors GMGW-1 exactly. Case 1 and Case 3 participants are asked to adapt the template to their use.

RECOMMENDATION: If your organization requires you to include slides providing background about the organization and its products, we recommend that those slides be placed at the END of your presentation.

Notice to Participants Regarding Open Publication

All mesh files, geometry files, and presentations from this workshop will be made publicly available after the workshop ends. We encourage open publication for the purpose of sharing results and inspiring participation in future workshops. Without open publication, the value of this series of workshops is greatly diminished.

If you require that your materials not be made publicly available, notify us in writing when you submit your presentation or at any time by emailing meshingworkshop@gmail.com.

Mesh Evaluation Software

During GMGW-1, a stand-alone mesh evaluation code was written the committee's use in evaluating unstructured meshes. If you want to use that software it is available for you to download from GitHub.

Mesh Resolution and Size

With respect to mesh resolution as defined by cell count, GMGW-2 will use a quantified terminology instead of the traditional qualitative terminology (e.g. coarse, medium, fine) that was designed to get us to 2030 resolution levels without the invention of extravagant superlatives (e.g. super extra fine). The details are explained in Mesh Size Naming Conventions for GMGWx in the Resources section of this website.

GMGW-2 will use the 2018 definitions of mesh resolution as summarized below.

Order Description Num. Cells (billions)
8.0 Coarse 0.100
8.5 Medium 0.316
9.0 Fine 1.000
9.5 Extra Fine 3.160
10.0 Super Fine 10.000
10.5 Hero 31.600

Promotional Flyer

Download this 1-page PDF informational flyer and share it with your CFD colleagues to help promote GMGW-2.

Due Dates

Participant's submissions for each case were due on 12 Nov 2018.

Each participant must submit an abstract for each case they will present at the workshop. A template for the abstract is provided below. Abstracts were due on 12 Nov 2018 and should have been emailed to meshingworkshop@gmail.com.
