INCLUDEIncludes an external input file, similar to #include in C preprocessor. More details. Show included file FILEfile to be included=./MuellerBrown-Potential.dat
# INCLUDE FILE=./MuellerBrown-Potential.dat
# vim:ft=plumedEnables syntax highlighting for PLUMED files in vim. See here for more details.
The INCLUDE action with label ./MuellerBrown-Potential.dat calculates somethingUNITSThis command sets the internal units for the code. More details NATURAL use natural units
The UNITS action with label calculates somethingscaling_factorThe CONSTANT action with label scaling_factor calculates the following quantities: Quantity | Type | Description |
scaling_factor | scalar | the constant value that was read from the plumed input |
