► OpenFOAM introductory training - Online seesion
  21 Aug, 2020
Online OpenFOAM introductory training


This course prepares the attendees to conduct end-to-end CFD studies, that is, CAD → Meshing → Simulations → Post-processing, using the OpenFOAM®.

This course is offered in cooperation with the University of Genova and Wolfdynamics (http://www.wolfdynamics.com). The course extends for five weeks (asynchronous learning).

This training session will take place during the months of October-November 2020.

More information at this link:
https://bit.ly/2QaAQPT


OpenFOAM® version: the course is based on OpenFOAM® version 8.

Teaching method: all the lectures have been pre-recorded so that the participants can follow the course at their own pace. However, we strongly recommend dedicating at least five hours a week (that is less than an hour a day) to cover each week's topics and follow the guided tutorials. The participants will have access to a dedicated forum where they can post questions or interact with other users. We will meet once a week for questions and answers (Q&A).

Q&A meeting times: we will meet online every Friday for Q&A (16OCT, 23OCT, 30OCT, 6NOV, 13NOV). To maximize users participation in different time-zones, the meetings will start at 3:00 pm CET and will end at 6:00 pm CET.

Training material: every participant will have access to the lecture notes (in pdf format) and all the supporting material (tutorials and videos).

Fees: in light of the current developments due to the COVID19 pandemic, we have decided to offer a special price to all participants, 200 Euros + VAT.

Grants: we are also offering two grants to follow the training for free (reserved to undergraduate and graduate students). If you are interested, send an email to guerrero@wolfdynamics.com.

► Thank you wyldckat, aka Bruno Santos!!
  20 Aug, 2020
wyldckat, aka Bruno Santos, has decided to hang-up his gloves and reduce his volunteer time supporting the OpenFOAM community. For many years Bruno has spent a lot of time to support users and share his knowledge, always without any thought of himself and always with a very friendly tone.

With more than 10,000 forum posts and the highest reputation of all forum users on CFD Online Bruno is without competition the person who has spent most time to support OpenFOAM users on CFD Online and share his knowledge. We are many who will miss Bruno. We at CFD Online will most certainly miss Bruno. He has been the main administrator for the OpenFOAM forums for a long time, handling both support and more administrative tasks like removing spam.

Please join me in thanking Bruno for all the free help he has given to so many users over so many years!! THANK YOU!! We owe you.

Good luck in the future Bruno! If you ever need a favor back please do not hesitate to ask. You have a large group of friends here.

Best wishes,

Jonas
► An open-source framework for data analytics, finite element and finite volume methods
    7 Jul, 2020
A program for 3 way coupling between open-source software Elmer FEM, OpenFOAM and Dakota has been developed. The program along with examples can be found here: https://github.com/AnjaliSandip/Elme...penFoam-Dakota




Capabilities: The interface provides an open-source framework that integrates data analytics, finite element and finite volume methods. This framework enables a richer understanding of multi-physics/phase predictions in a time sensitive manner. Its key features include uncertainty quantification, surrogate modeling, parallel programming and robust post-processing capabilities.

► Monthly informal OpenFOAM meeting
    3 Jul, 2020
Hi everyone,
during the last openfoam workshop there was a discussion about a support group for beginners. Despite I already work for some time with openfoam I still consider myself a beginner. In order to give people an informal way to discuss their experience or problems with openfoam I would like to invite everyone to a monthly video conference. In order to allow participation of people from many time zones I propose to do it in the afternoon of Europe time.
The first occasion will be in the 24th of July at 16:00 central European summer time. The details of the Zoom Meeting room can be found in the attached image.


Everyone is welcome.
See you there.
Patrick

► Flowfusic - OpenFOAM in a cloud from web browser
    1 Jul, 2020
Dear All,

First of all, it is high time to say hello. I've been using OpenFOAM and this forum for years and I've always found a solution to my endless problems during my PhD.

Many thanks to all of you who contributes to this community.

Now, here I am asking for help.

Currently, I am working on my own project which aims to bring OpenFOAM to cloud accessible from a web browser:

www.flowfusic.com

It is extremely easy to start using OF with Flowfusic, after login you'll get a terminal, file manager, and text editor.

I need feedback from OF users. If you are interested in testing or using it please send me a private message and I will give you premium access.

Many thanks,
Maciej

  • Each training session will be split into two non-consecutive days.
  • Attendees are required to bring their computer with OpenFOAM pre-installed. We will prepare a video to help the participants to install OpenFOAM and any additional application that will be used during the training.
  • The inscription fee includes the training material (in pdf format), and access to all supporting material (tutorials and videos).
  • Also, many of you or your colleagues may have been forced to be off work during this challenging period; therefore, we have decided to adjust our training fees and offer a 20% discount in all advanced training sessions.


With this in mind, we want to draw your attention to the upcoming OpenFOAM advanced online training sessions that will take place in July-August, 2020. During these online training sessions, we will address the following topics:

  • JUL15-17 2020. Turbulence modeling in general CFD and OpenFOAM® - Theory and applications.
  • JUL20-22 2020. Multi-phase flows modeling in general CFD and OpenFOAM® - Theory and applications.

  • AUG7-10 2020. Moving meshes, rigid body motion, adaptive mesh refinement, and overset meshes.


So hurry up and book your place, you are still on time to take advantage of our reduced fees.

For more information or to book your seat visit the following link,



Prerequisites: intermediate knowledge of CFD, OpenFOAM, and Linux is required. Some basic knowledge of C++ and shell scripting is beneficial. For those following the optimization training, no prior knowledge of Dakota is required.

Location: online.


Time-zone: Central European Time (CET).

Course times: to maximize users participation in different time-zones, the courses will start at 2:00 pm CET and will end at 5:30 pm CET. Each training session will be split into two non-consecutive days.


Language: English

Number of seats: 7 places available.

Training material: every participant will have access to the lecture notes (in pdf format), and to all supporting material (tutorials and videos).

Teaching method: lectures and hands-on sessions to validate the acquired knowledge. A training certificate is provided to all attendees who complete the course.


Additional information:
  • Cancellations will not be accepted.
  • Attendees are required to have all applications installed.
  • To maximize the learning process, it is recommended to use two devices. One device to run all tutorials and the other device to follow the online meeting.
  • To deliver the training, we will use Cisco WebEx, GoToMeeting, or Zoom online conferencing applications, that are free on the client side.
  • For remote control, we will use anydesk, which is free on the client side.

Since I'm privately interested in numerically solving fluid dynamic problems, I wanted to have a deeper look at the solvers available in OpenFOAM.  By doing this I thought that maybe I could update the description of the solver in this page.
