Hello I have a question,
I want to work on ICY which is the interface between COMSOL and YADE. But when I want to run COMSOL from terminal, and I wrote "comsol mphserver" on teminal, I get this "comsol: command not found" how can I solve this?
and when I want to work on python, in terminal I put "python server.py" but it gives me this error" Command 'python' not found, did you mean:
command 'python3' from deb python3
command 'python' from deb python-is-python3"
Then I put his command on terminal "python3 server.py" and then it gives me this error "File "/home/geology/Downloads/verification codes training/client-server/server.py", line 39
print 'command: '+command
^^^^^^^^^^^^^^^^^^^^^^^^^
SyntaxError: Missing parentheses in call to 'print'. Did you mean print(...)?". How can I solve these problems.
Negin Mondegari Sharifabad The first error, "comsol: command not found," indicates that the terminal does not recognize the comsol command because it is not in the system's PATH. To resolve this, add the directory containing the comsol executable to your system's PATH.
You may accomplish this by including the following line in your.bashrc file:
export PATH=$PATH:/path/to/comsol/bin
For the second problem, it appears that you have both python2 and python3 installed on your machine, with the terminal defaulting to python2. That's why it gives you the error "Command 'python' not found, did you mean: command 'python3' from deb python3 command 'python' from deb python-is-python3".
You may experiment with python3 by typing "python3 server.py" instead of "python server.py," as you have.
The third blunder "SyntaxError: No parenthesis in 'print' call. Did you intend to say print(...)?" Python3 employs parenthesis for print statements rather than simply the keyword.
To correct this mistake, replace all instances of 'print' in your script with 'print()'.
You might also try using a virtual environment to tackle similar problems. It will set up an isolated environment for your project and supply you with a customized version of Python as well as any required libraries. This will also avoid problems with other system-wide libraries.

It seems that you are running into some issues when trying to run COMSOL and a Python script on Ubuntu.
Regarding the "comsol: command not found" error, it is likely that the COMSOL application is not installed in the system PATH. This means that the command line does not know where to find the comsol executable. A few things you can try:

Regarding the python errors you are getting:
@Abderrahmane Boudribila Thank you for your answer, I can open COMSOL on my Ubuntu but whe I follow your instructions I faced a problem. The directory of installation COMSOL on my ubuntu is home//Public/COMSOL56/Multiphysics/bin and when I go to my bib folder I didn't see any comsol mphserver. when I copy this command on terminal : "'/Public/COMSOL56/Multiphysics/bin/comsol mphserver'" terminal gives me an error of "bash: /Public/COMSOL56/Multiphysics/bin/comsol mphserver: No such file or directory". and again when I try 'export PATH=$PATH:/Public/COMSOL56/Multiphysics/bin' this command shows to me on terminal "comsol: command not found"
