WebThis fix computes a global scalar which can be accessed by various output commands. The scalar is the spring energy = 0.5 * K * r^2. This fix also computes global 4-vector which can be accessed by various output commands. The first 3 quantities in the vector are xyz components of the total force added to the group of atoms by the spring. WebThe fix_modify energy option is supported by this fix to add the energy stored in the per-atom springs to the global potential energy of the system as part of thermodynamic output. The default setting for this fix is fix_modify energy no. The fix_modify respa option is supported by this fix. This allows to set at which level of the r-RESPA ...
