4th NGSolve Usermeeting#

Thank you for the great Usermeeting. Talks can be rewatched on our YouTube channel!

Synopsis#

This user meeting is the successor of the first three user meetings in Vienna and Göttingen and is the first user meeting outside Europe. After the COVID pandemic, the 2023 NGSolve User Meeting finally arrives in Portland, Oregon, USA from July 9th - July 11th, 2023. We bring together newcomers and advanced NGSolve users. Scientists from different backgrounds are expected. Newcomers will benefit from tutorials providing a quick start into NGSolve and its Python interface. Researchers at the frontiers of numerical methods will benefit from advanced tutorials. Experiences will be shared, new features will be discussed, and extensions to the software will be presented.

Participants#

Here is the List of participants.

Lodging#

A limited block of rooms are held for this workshop at Hotel Vance located at 1455 SW Broadway, a five-minute walk from the workshop venue. The negotiated rate of 169 USD per night can be obtained through this link, on a first-come first-serve basis, for reservations during the period covering July 8 through July 11, 2023:

An alternate option is Hotel Zags, located nearby at 515 SW Clay Street. You can obtain their discounted rate by putting PSU into the box for “Corporate/Promo” code while booking at their website.

The conference venue is located at the southern end of downtown Portland, where there are many more lodging options, all accessible by a quick internet search.

Travel#

The conference venue is located in downtown Portland, about a 25-minute drive from the Portland International Airport (airport code PDX). From the airport, a light rail transit line, called the MAX Red line, will get you to downtown for USD 2.50. During the workshop dates, there may be track construction that prevents the MAX Red line train from reaching the airport, in which case there will be a shuttle bus to the next available train stop from the airport. Taxis from the airport to downtown cost between USD 40-50. Uber and Lyft also provide pickups from the airport. Real-time public transit information on light rail lines, a separate streetcar system, and various bus lines is available at Trimet. This information is also tracked by apps like Google Maps in real time.

Regional participants can also travel by long-distance trains directly into downtown Portland Amtrak Union Station (located at 800 NW Sixth Ave) or by long-distance bus companies, like BoltBus, FlixBus, and Greyhound.
