Bulk Modulus
Description
This function calculates the bulk modulus of a system upon the deformation of the simulation box. For this purpose, a Gromacs simulation node with an activated Deformation on all three axis must be provided as parent node. Note that the barostat must be deactivated in the Gromacs simulation node. Finally, the user must provide a maximum relative expansion of the cell expressed as a percentage, which cannot be larger than 10%.
