I've written about this several times... one of them here: Advanced tips for working with the OpenFOAM shell environment

no as you know my other versions of OF were deleted when I wanted to install a anti-filter software.I just download them again.but in oenfoam.org i see only 2.2.0 version for download or maybe i haven't look at it carefully?

If you need OpenFOAM 2.1.1, follow these instructions: http://www.openfoam.org/archive/2.1....oad/ubuntu.php

dear Bruno I used alias as you have told.but no command executed now:

ehsan@Ehsan-com:~/Desktop/Huge_reservoir_filling$ runPlot 4 rhoCentralFoamModified
Usage
=====
  pyFoamPlotRunner.py [options] <foamApplication> <caseDir> <caseName> [foamOptions]

pyFoamPlotRunner.py: error: Too few arguments (3 needed, 1 given)
ehsan@Ehsan-com:~/Desktop/Huge_reservoir_filling$ decomPosePar
decomPosePar: command not found
ehsan@Ehsan-com:~/Desktop/Huge_reservoir_filling$ of220
of220: command not found
ehsan@Ehsan-com:~/Desktop/Huge_reservoir_filling$ alias of220='. /opt/openfoam220/etc/bashrc'
ehsan@Ehsan-com:~/Desktop/Huge_reservoir_filling$ decomPosePar
decomPosePar: command not found
ehsan@Ehsan-com:~/Desktop/Huge_reservoir_filling$

-----------------------
sorry.I had written alias commands in shell not in bashrc.now resolved.

1. What are the last 10 lines of the file "~/.bashrc"?
2. Did you start a new terminal?
3. It's "decomposePar", not "decomPosePar".

[immortality]

is it true and as you had told?

if [ -f ~/.bash_aliases ]; then
    . ~/.bash_aliases
fi

# enable programmable completion features (you don't need to enable
# this, if it's already enabled in /etc/bash.bashrc and /etc/profile
# sources /etc/bash.bashrc).
if [ -f /etc/bash_completion ] && ! shopt -oq posix; then
    . /etc/bash_completion
fi
#. /opt/openfoam220/etc/bashrc
#. /opt/openfoam211/etc/bashrc
#. /opt/openfoam210/etc/bashrc
alias of220='. /opt/openfoam220/etc/bashrc'
alias of210='. /opt/openfoam210/etc/bashrc'
export PATH="$PATH:/home/ehsan/Desktop/codes"

The contents of the file "~/.bashrc" look OK. There doesn't seem to be any problem with it.

Whenever you start a new terminal window (or tab), run:

of220

or:

of210

for activating the respective environment.

If you need the other version of OpenFOAM to work with, start a new terminal and activate said version. You'll only be able to use one version at a time per terminal.

So, if you have not yet started a new terminal, you better start a new one now!

It's been so much time since you've been working on Linux, and you still don't know about terminal tabs?
