hi guys, i had some issue before, trying to install openfoam with docker, so i am trying now to install by source.
i am following step by step all informations on the site:
i installed everything from prerequisities section,
i dowloaded openfoam and thirdparty, and unpacked then in my home.
i have the two folders in my home and i entered the line source source ~/OpenFOAM/OpenFOAM-v1812/etc/bashrc in my bashrc

so what now? i didn't understand how can i build and compile openfoam
could you explain step by step?
it's not clear at all

Quick questions:

1. Which Linux Distribution are you using?
2. Which installation instructions are you following?

Yes, you need to source every time you open a new terminal, unless you include the sourcing line in your .bashrc file.

Best,

hi pablo i did have the same problem with OpenFoam 1812
i wrote the same in terminal and i recieve the same error text.
so, what should i do? include the line source ~/OpenFOAM/OpenFOAM-v1812/etc/bashrc in my bash?
but i don't understand, where should i past this line?

hi guys so, the main problem i had, compiling open foam is that:

i unpack the folders, i open terminal in my home, in the openfoam folder and i write

source ~/OpenFOAM/OpenFOAM-v1812/etc/bashrc

that's what i get in return;

no completion added for /home/myname/OpenFOAM/OpenFOAM-v1812/platforms/linux64GccDPInt32Opt/bin
... incorrect platform, or not yet compiled?

so what should i do now? go on with the installation?

because other users adviced me to past and save the line
source ~/OpenFOAM/OpenFOAM-v1812/etc/bashrc in my bashrc
should i do that before start compiling? or after?

another question, where should i past it in my bashrc? at what number line?

Yes you either need to source it every time you open a terminal or you put it into one of your bash scripts (which does it automatically).

If you have no idea where it goes, then put it at the bottom or end of your existing bash file. That's because everything in the bash files get executed when the terminal is opened. If you type commands into the terminal (after you open a terminal) then everything in the bash file has already been executed. Putting it at the bottom of your bash reproduces this order.

The line doesn't strictly have to be at the bottom, but without knowing the contents of your bash file, we can't say. We have no idea what other sourcing you are already doing.

Depending on your setup this can be the bash file bashrc file or localsh file. Personally I prefer localsh.


Have you already compiled openfoam or are you currently compiling openfoam? The first time you source openfoam this way, you'll of course get a lot of messages for things that don't yet exist. Compile openfoam and then they should go away the next time.

i compiled and all was great, i tried to make run first simulation, elbow, i used the command fluentMeshToFoam and it worked very good.
but then i closed the terminal, i tried again, and i got the message:

"the command fluentMeshToFoam can't be found but you can install with sudo apt install openfoam"
if i do i use the version 4.0 and not the 18.12

hi there i am trying to install Paraview 5.6 on xubuntu, after compiling openfoam18.12

./makeParaView that's what i get at the end of the install process

Quick answer: I don't have step-by-step installation instructions for OpenFOAM-v1812, but you can find similar ones for the previous version v1806 here: https://openfoamwiki.net/index.php/I...u#Ubuntu_18.04
You can try and read/follow them, to get a better sense of how building from source code can be done.

Hello Bruno,
I also install OF1812 in Centos 7 without admin rights,
