Hi, I am new to Ubuntu as well as openFoam
I installed ubuntu 14.04 LTS and after that openfoam 2.3.1
then instead of installing paraviewopenfoam 410 I installed paraviewopenfoam 50. I thought it would give a better view for post processing.
But it is not working. What I understood is because the openfoam 2.3 have inbuilt configuration for paraview 4.1
can someone teach me how to make openfoam 2.3 work with paraview 5.0, if it is possible? or do i have to install paraview 4.1?

Quick answer: If you only have ParaView 5 from the OpenFOAM 4.1 deb packages, then that means that you need to use the built-in reader, by running the following command:

paraFoam -builtin

This is so that it uses the file extension ".foam", to use the built-in reader.

The file extension ".OpenFOAM" is meant to be open in ParaView with OpenFOAM's reader, which is part of OpenFOAM's own installation, because it links directly to "libOpenFOAM.so".

You can have 2 OpenFOAM versions installed and switch between them as instructed here: http://openfoamwiki.net/index.php/In...with_the_Shell

Thanks...

But, It dint work

I used the code >>>sudo apt-get install paraviewopenfoam50<<< in terminal to install paraview

now, when i type the command paraFoam -builtin
I got the message as follows
>>>
created temporary 'simple.foam'
/opt/openfoam231/bin/paraFoam: 265: /opt/openfoam231/bin/paraFoam: paraview: not found

<<<
(simple is the folder in which i opened terminal)

// I am having an amd radeon graphics card and last time when i was using paraview 4.1, it will only pick the intel graphics card,which is inbuilt. then, when i am doing some operation in paraview, it closes with a message that there was some error with intel graphics.
So, I uninstalled ubuntu and re installed it plus openfoam231 and then instead of paraview410 installed paraview50 hoping it will work.. but then I saw there are files in openfoam231 which calls paraview410 and no files for 50


Thanks again...

Greetings ad2eb,

My apologies, I didn't think through all of the details when I wrote my previous post And sorry for the delay in getting back to you on this.

In order for ParaView 5.0 from OpenFOAM 4 to be picked up on OpenFOAM 2.3.1, you need to edit the file "/opt/openfoam231/etc/config/paraview.sh" and change the version number... you can do that simply by running the following commands:

sudo sed -i  -e 's/ParaView_VERSION=4.1.0/ParaView_VERSION=5.0.1/' -e 's/paraviewopenfoam410/paraviewopenfoam50/' /opt/openfoam231/etc/config/paraview.sh

If you already have loaded/sourced/activated the shell environment for using OpenFOAM 2.3.1, then you can update the environment variables by running:

wmSET

Best regards,
Bruno

[ad2eb]

Thank you for the response..


as again, there is a slight problem...
but, this time I am sure your command did work properly

when I tried to open paraFoam
an error message came..

>>>
FATAL ERROR: ParaView reader module libraries do not exist

Please build the reader module before continuing:
cd $FOAM_UTILITIES/postProcessing/graphics/PV5Readers
./Allwclean
./Allwmake

<<<

So I understood the problem (somewhat )
and I executed the first command >> cd $FOAM_UTILITIES/postProcessing/graphics/PV5Readers

but then the error message was

>>>

bash: cd: /opt/openfoam231/applications/utilities/postProcessing/graphics/PV5Readers: No such file or directory

<<<

So I went to the folder and checked. I could find PV4Readers folder. I guess it is like this --> Along with openfoam231 package, 'PV5Readers' is not automatically downloaded.
So, If I need PV5Readers, I need to separately get it.

But, I don't know how to do it.

Thanks again. (I know you are a very busy person and I really appreciate that you replied. )


Edit: I checked in github and other places. could not find PV5Readers folder. I could find PV3,PV4 and simply PVReaders folders. I even downloaded the source pack of 4.0 from https://openfoam.org/download/4-0-source/ . but even there, PV5Readers folder is not present. did I make some mistake..?

[wyldckat]

Hi ad2eb,

Did you follow the instructions I wrote in the other post? Namely what I wrote in post #2?

Best regards,
Bruno

[ad2eb]

Yup..
I typed the first command in terminal, then had to enter my sudo password..
then typed the second command

do i want to redo it..?
or will redoing it create any problem..?

[wyldckat]

Quick request: Please post the contents of the file "/opt/openfoam231/etc/config/paraview.sh", so that I can take a look at what it has right now in your installation.

Quick answer: Sorry, I had a complicated+busy week and weekend

The file looks like it is properly written and defined. Please run the following command, to confirm if the ParaView 5.0.1 from the OpenFOAM 4.1 Deb package is installed or not:

ls -l /opt/paraviewopenfoam50/bin/paraview

[ad2eb]

Thanks...
(Its okay that you are responding )

when I typed, this is the output
-->
-rwxr -xr-x 1 root 84653 Jun 25 2016 /opt/paraviewopenfoam50/bin/paraview

<--

I don't understand that what it means by that anyways

[wyldckat]

Quick answer: Sorry, only today have I finally managed to come by and look into this.
Please activate the OpenFOAM 2.3.1 environment, go into the case folder you want to use and then run:

paraFoam -builtin

This will ensure that the ".foam" file extension is used and should not give the message that you've been getting in the past.

Because if you only run:

paraFoam

it will complain about the missing "ParaView reader module libraries".


Edit: I forgot to mention that my previous request was for seeing if ParaView 5 was really installed or not, which is why it gave a bit of cryptic information. The "-rwxr -xr-x 1 root" means that "root" has "rwx" access (read-write-execute), while all in group and others "r -xr-x" have read-execute permissions only, which is enough for you to run ParaView 5 as a normal user.

[ad2eb]

builtin command is working
thanks...
also, I installed paraviewopenfoam410

and slightly modified your code to change paraview.sh

now parafoam itself is working

After that i tried to install fglrx catalyst and screwed up my ubuntu
need to re install from scratch
thanks for your help
next time, will try in a better way
