A filename, including either absolute or relative path specifications.
The open command opens a SILO file and associates it with the current MeshTV output window. All successive plots produced in the current output window will obtain data from the specified SILO file.
A SILO file is typically generated by a physics simulation application, and can contain physics meshes, variables associated with those meshes, subdirectories, curves, material data, and so on.
Previously opened SILO files are closed when a new open command is issued. To open a file without closing previously opened files, use the addframe command.
