"Overview"
|
|
"<div align=\"justify\">LAMMPS GUI is a graphical text editor that is "
|
|
"linked to the LAMMPS library and thus can run LAMMPS directly using "
|
|
"the contents of the text buffer as input through the LAMMPS C-library "
|
|
"interface. This makes it convenient to use for beginners and during "
|
|
"tutorials</div><br><br>"
|
|
"Features"
|
|
"<div align=\"justify\">The main window of the LAMMPS GUI is a text "
|
|
"editor window with syntax highlighting. The output of a LAMMPS run is "
|
|
"captured and displayed in a log window. The log window is updated "
|
|
"regularly during the run, as is a progress bar in the main window. "
|
|
"After the simulation is finished, an image of the simulated system "
|
|
"can be created and shown (and saved) in image viewer window. Ongoing "
|
|
"runs can be stopped at the next run iteration.</div><br>"
|
|
"<div align=\"justify\">When opening a file, the editor will determine "
|
|
"the directory where the input file resides and switch its current "
|
|
"working directory to that same folder. Many LAMMPS inputs contain "
|
|
"commands that read other files, typically from the folder as the "
|
|
"input file. The GUI will show its current working directory. "
|
|
"In addition to using the menu, the editor window also receive files "
|
|
"as the first command line argument or via drag-n-drop from a "
|
|
"graphical file manager GUI or a desktop environment.</div><br>"
|
|
"<div align=\"justify\">Almost all commands are accessible via hotkeys. "
|
|
"Which those hotkeys are, is shown next to the entries in the menus. "
|
|
"Log and image viewer windows can be closed with CTRL-W (or Command-W "
|
|
"on macOS).</div><br>"
|
|
"<div align=\"justify\">The 'About LAMMPS' dialog will show the "
|
|
"LAMMPS version and the features included into the LAMMPS library "
|
|
"linked to the LAMMPS GUI.<br><br>"
|
|
"Due to its nature as a graphical application, it is <b>not</b> "
|
|
"possible to use the LAMMPS GUI in parallel with MPI, but OpenMP "
|
|
"multi-threading is available.</div>");
