Hi,
As you are looking for a .so, I assume that you are on a linux distribution. If yes, as the LinearElasticity software doesn’t install the libElas in a standard place (such as /usr/local/lib or /usr/lib), I think that you have to add the directory in which libElas.so can be founded to your LD_LIBRARY_PATH.
For example, if libElas.so is installed in $HOME/lib, you can add this directory with the command:
export LD_LIBRARY_PATH=$HOME/lib:${LD_LIBRARY_PATH}
Then I hink that Mmg will run.
To ensure that the LinearElasticity install directory is always added to the LD_LIBRARY_PATH, you can add the previous export command to the configuration file of your shell interpreter (.bashrc, .zshrc…).
Do not hesitate to close the thread if it works or to contact me again if not.
Best Regards,
Algiane
