► New OpenFOAM PhD Thesis available: Multiphase mass transfer
    6 Oct, 2020
Hello everyone,
I successfully defended my PhD thesis last year and it has been published in the beginning of this year.
It was just recently that I looked back at the amount of help and information I received from the cfd-online community.
I would therefore like to share the link to my thesis here in the hope that it might help someone with their research.

You can find the online version under the following doi: https://doi.org/10.14279/depositonce-9576.

Topics include:
- hydrodynamic multiphase (water/air) simulations using interFoam
- transport and mass transfer simulations
- solver customisations for a mass transfer solver to account for the specifics of H2S (hydrogen sulphide) mass transfer

I hope this material is useful to you and I am open to suggestions or questions about the topics presented in the thesis.

Thanks for all the help and the amount of information available in this community.
Best wishes
Katharina Teuber
► 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.



Hurry up and get your seat now!
► 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

New page

'''rhoSimpleFoam'''

rhoSimpleFoam is a steady-state solver for compressible, turbulent flow, using the SIMPLE (Semi-Implicit Method for Pressure Linked Equations) algorithm.
In the newer releases it also includes an option to use the SIMPLEC (Semi-Implicit Method for Pressure Linked Equations Consistent) algorithm.
It is a pressure based compressible solver. That means that a pressure equation is solved and the density is related to the pressure via an equation of state.
