VisIt - Introduction
VisIt is a free interactive parallel visualization and graphical analysis tool for viewing scientific data on Unix and PC platforms. Users can quickly generate visualizations from their data, animate them through time, manipulate them, and save the resulting images for presentations. VisIt contains a rich set of visualization features so that you can view your data in a variety of ways. It can be used to visualize scalar and vector fields defined on two- and three-dimensional (2D and 3D) structured and unstructured meshes. VisIt was designed to handle very large data set sizes in the tera- to peta-scale range and yet can also handle small data sets in the kilobyte range. More about VisIt here
Note: Some browsers immediately will untar the tarred visit file, whereas the script expects to find an tarred file. Make sure that when you are prompted about unarchiving that you do not choose that option, but instead save the archived file.
Note: It is convenient to have the downloaded file and the script in the same folder (In this case it is home folder)
For Mac 10.6.8:
>> cd ~
>> chmod 700 visit-install
>> mkdir visit
>> ./visit-install 2.3.0 darwin-x86_64 ./visit
Installation of VisIt starts here. Choose '1' if you don't want to add profiles on remote computer. Then after that it asks 'Do you need to use a bank when submitting parallel jobs to a batch system?'. Incase of CMT the answer is no so you type in 'n' To move visit to your Applications folder
mv ./visit /Applications
Congratulations! You have successfully installed VisIt.
OR If visit were installed in the directory "/Applications/visit", then the following commands would set your path appropriately.
>> echo "set path = ($path /Applications/visit/bin)" >> .cshrc
>> VisIt Path(local): The path to your local VisIt installation.(/Applications/visit)
For more information read this: This will unpack the downloaded tar file and install VisIt in the specified directory. Note that it can create a new distribution directory or update an existing distribution. This is handled automatically. The command to run the script is,
>> visit-install "version" "platform" "directory"
Note that you will need to have the file "visit2.3.0.darwin-i386.tar.gz" present in the current directory for this to function properly.
