► 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

► OpenFOAM advanced training - Online. July-August, 2020 (https://bit.ly/2CcYQ11)
  16 Jun, 2020
While we all adjust to the new normal of the COVID19 pandemic and due to the travel restrictions imposed by many countries, we have decided to cancel all the classroom training sessions programmed during the year. All the training sessions will be delivered online.

  • The training sessions will be delivered starting from mid-July until the beginning of August.
  • The course is delivered live. However, all sessions will be recorded.
  • 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.
  • 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.
  • JUL24-27 2020. Introduction to the FVM method. Standard practices in general CFD with applications to OpenFOAM.
  • JUL29-31 2020. Introduction to solid modeling for general CFD and meshing using OpenFOAM® technology - Onshape and snappyHexMesh.
  • AUG3-5 2020. Design of experiments, space exploration, knowledge extraction, and numerical optimization using Dakota - Code coupling Dakota-OpenFOAM.
  • 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.
  • A training certificate is provided to all attendees who complete the course.
  • Support to install the required applications can be provided at a nominal price. Send us an email for more information.

► QGDsolver - OpenFOAM computational framework for fluid flows based on regularized equ
  25 May, 2020
QGDsolver is OpenFOAM framework for simulation of fluid flows using regularized equations approach. It contains library for approximation of partial derivatives at face centers of unstructured grids and a set of OpenFOAM solvers:
  • QGDFoam - solver for compressible viscous perfect gas flows in a wide Mach number range - from 0 to infinity
  • QHDFoam - solver for incompressible viscous fluid flows with buoyancy force
  • particlesQGDFOam - solver for compressible viscous perfect gas flows in a wide Mach number range with particles - from 0 to infinity
  • particlesQHDFoam - solver for incompressible viscous fluid flows with buoyancy force with particles
  • SRFQHDFoam - solver for incompressible viscous fluid flows in rotating frame of reference with buoyancy force
  • QHDDyMFoam - solver for incompressible viscous fluid flows in domains with deforming boundary and with buoyancy force
  • interQHDFoam - solver for incompressible 2-phase viscous fluid flows with buoyancy force and surface tension
  • reactingLagrangianQGDFoam - solver for reacting multicomponent compressible viscous perfect gas flows in a wide Mach number range with particles - from 0 to infinity
  • scalarTransportQHDFoam - solver for scalar transport equation to demonstrate the very basics of QGD/QHD equations principles

Generally speaking, QGD/QHD framework offers an alternative to PISO/SIMPLE and Riemann-solvers approach to simulate various flow phenomena on unstructured grids. And sometimes it could be superior comparing to mentioned techniques.

The framework could be downloaded HERE: https://github.com/unicfdlab/QGDsolver

The presentation covering some theory and basics of the implemeted approach could be downloaded HERE: https://github.com/unicfdlab/QGDsolver/blob/master/qgd-framework-2020-final.pdf

Please, do not hesitate to ask for assistance on how to setup the case or on how to derive new equations for your problem using regularized hydrodynamic approach

Ubuntu 20.04 does not supply gcc/g++5 in its repository.
  +

The gcc5 toolchain can be installed from the 18.04 repositories. Be aware that this may break some dependencies in rare cases.
  +
  +
In order to include the 18.04 repositories create a file <bash>bionic_legacy.list</bash>  in <bash>/etc/apt/sources.list.d</bash> which contains the line:
  +
  +
<bash>
  +
deb http://gb.archive.ubuntu.com/ubuntu/ bionic universe
  +
</bash>
  +
  +
then update the apt package lists:
  +
  +
<bash>
  +
apt update
  +
</bash>
  +
  +
After that follow instructions for Ubuntu 18.04 above.
