Hi OpenFOAM users!

I am new on OpenFOAM, Paraview and also on CFD Online.
I have just install on my Ubuntu system, the softwares OpenFOAM 2.3.0. and also ThirdParty-2.3.0 where we find ParaView-4.1.0.

Question 1:
Where can I find the launcher of ParaView? Shall I each use the terminal to run an example?

After the installation of OpenFOAM, I try to run an example from /user-2.3.0/run/tutorials/incompressible/icoFoam/cavity.

I use on the Terminal these words:

cd $FOAM_RUN/tutorials/incompressible/icoFoam/cavity
blockMesh
icoFoam
paraFoam

Then, the window of ParaView viewer appears. I cannot click on the apply button. And on the directory cavity, it appears new sub-directories (0.1 , 0.2 , 0.3 , 0.4 and 0.5).


Question 2:
Do the application apply the example automatically when I entered the words on the Terminal?

I think that because the different sub-directories 0.1 0.2 ... etc corresponds respectively to the state of the example at t=0.1s , t=0.2s ... etc

Regards.

Jeff.

Greetings Jeff and welcome to the forum!

Regarding your questions:

1. When using OpenFOAM, starting ParaView is done by running this command:
   

   paraFoam

   Make sure the "cavity.OpenFOAM" entry in the "Pipeline Browser" is selected. Then you should be able to click on the "Apply" button.
2. The time folders are automatically recognised by the reader in ParaView. The time controls are usually on the top centre-right of the ParaView window.

For more information on how to use ParaView: http://www.paraview.org/Wiki/ParaVie...le_Of_Contents
For more information on how to use the command line: http://linuxcommand.org/learning_the_shell.php

Best regards,

Hi wyldckat,

Firstly, thank you for your help.

About my first question, to use Ubuntu is really different than Windows and I realize it because we need to use command line.

Regarding my second question, on the version of OpenFOAM I use (2-3-0), apply button runs automatically. "cavity.OpenFOAM" entry in the "Pipeline Browser" is selected and time folders are recognized too.

I will use your links in order to improve my understanding of this software.

Just a last question: I want use this software to make finite elements analysis on different models that I design on Catia, a design software. Could I import easily a model from the software or do I need to reproduce myself the model on the foamfile named blockMeshDict?

Regards,

Jeff.

Hi Jeff,

Next time you have a question that is not directly related to the topic being discussed in a thread, please search for another similar thread to the new topic or start a new thread. This is because it makes it easier for people to find either your questions and or the given answers...

OpenFOAM uses the Finite Volume Method (mostly used in CFD) and not the Finite Element Method (most used in structural simulations). Therefore, you might want to first figure out what exactly you want to simulate.
... although the variant foam-extend does have some FEM implementation...

As for setting up a case based on a designed model, for example, read the tutorials given here: http://openfoamwiki.net/index.php/Sn...als_and_Guides

In fact, I want to run and parameter a stress analysis, the beamEndload exemple, in order to compare OpenFOAM with another FEA software like Abaqus or MSc Software where I will do the same exemple.

As to respect your condition, I send all questions in the dedicated thread -> http://www.cfd-online.com/Forums/ope...tml#post491478
