MoFEM doesn't run. Ubuntu 20.04

[Sergei Trushin]

Dear sirs,

I am currently trying to run MoFEM on my laptop, but with no succsess. I've installed developer version with Spack. 
I am using Ubuntu 20.04 installed next to Wondows. 

1. I tried to run both examples from the website for developer version. It sais that there is no such file or direcory:

sergei@sergei-N552VW:~$ cd mofem_install/mofem-cephas/mofem/users_modules/um-build-RelWithDebInfo-q5srxjr/basic_finite_elements/elasticity

sergei@sergei-N552VW:~/mofem_install/mofem-cephas/mofem/users_modules/um-build-RelWithDebInfo-q5srxjr/basic_finite_elements/elasticity$ ./elasticity -my_file LShape.h5m -my_order 2

bash: ./elasticity: No such file or directory

2. I tried to run an example from youtube as well, but terminal doesn't recognise "cubit &" command. 

sergei@sergei-N552VW:~/mofem_install/mofem-cephas/mofem/users_modules/um-build-RelWithDebInfo-q5srxjr/basic_finite_elements/elasticity$ sudo cubit &

sergei@sergei-N552VW:~/mofem_install/mofem-cephas/mofem/users_modules/basic_finite_elements/elasticity$ cubit &

[1] 6843

sergei@sergei-N552VW:~/mofem_install/mofem-cephas/mofem/users_modules/basic_finite_elements/elasticity$ cubit: command not found

What might be the problem?
Thank you in advance

It seems like your code is not compiled (make command) because executable elasticity isn't there. 
For the cubit command to work, you would need to instal Cubit first. This is not open-source software. 

[Andrei G. Shvarts]

Just to add - Cubit is not open-source, but is available for free for student use: https://coreform.com/products/coreform-cubit/free-meshing-software/

Thank you for your answer.

Sorry, I am new in Linux and doesn't have an experience with terminal.
How should I proceed to at least run an example from website?

I did what is said in the instruction:

• Change mode of the script (if neccesary)
  chmod +x install_mofem_developer.sh
• Run the script (sudo privileges may be required)
  ./install_mofem_developer.sh
• Test run elasticity program
  cd YOUR_INSTALLATION_DIRECTORY

  cd mofem_install/mofem-cephas/mofem/users_modules/um-build-RelWithDebInfo-abcd1234/basic_finite_elements/elasticity

• ./elasticity -my_file LShape.h5m -my_order 2

• where abcd1234 in um-build-RelWithDebInfo-abcd1234 is the package hash and can different every time you install MoFEM.

Hello,

Can you do

cd /home/sergei/mofem_install/mofem-cephas/mofem/users_modules/ 

git checkout develop 

git pull 

cd /home/sergei/mofem_install/mofem-cephas/mofem/users_modules/um-build-Debug-bj5r4v7 

make -j2 2>&1 | tee  log_make

make install

ctest -VV 2>&1 | tee log_ctest 

and send log_make and log_ctest files,

Lukasz

[Sergei Trushin]

For some reasons I cannot attach log files...It sais "Error while posting a message".
Do I need certain permission or something? 

Lukasz, I will send you logs in Teams

[Lukasz Kaczmraczyk]

All was working when I looked into your log files. Now you have to compile the Release version

cd  /mofem_install/mofem-cephas/mofem/users_modules/um-build-RelWithDebInfo-q5srxjr/

make -j2 2>&1 | tee  log_make

make install

ctest -VV 2>&1 | tee log_ctest

Thank you, Lukasz!

It seems to be working now
