For general updates I use:
sudo apt-get update
But I want to update my Ovito software from 2.3.2 to 2.6.2, which is not achieved by the above command.
How can I update a particular software through Terminal in Ubuntu 16.04 LTS?

For just upgrading a single package, do:
sudo apt-get install <package_name>
For example:
sudo apt-get install dos2unix
One caveat is that this will of course install the package if not installed already, to only upgrade a package (and not install the package if not installed):
sudo apt-get install --only-upgrade <package_name>
For example:
sudo apt-get install --only-upgrade dos2unix
Also note that, sudo apt-get update does not upgrade a package to the latest version, it just synchronizes the package lists (and metadata) between the repositories and local files.
Perhaps you meant:
sudo apt-get upgrade
which will upgrade all packages to their latest versions.
