Styles with a gpu, intel, kk, omp, or opt suffix are functionally the same as the corresponding style without the suffix. They have been optimized to run faster, depending on your available hardware, as discussed on the Accelerator packages page.
WebLAMMPS is a classical molecular dynamics code with a focus on materials modeling. It's an acronym for Large-scale Atomic/Molecular Massively Parallel Simulator. LAMMPS has potentials for solid-state materials (metals, semiconductors) and soft matter (biomolecules, polymers) and coarse-grained or WebLAMMPS, or Large-scale Atomic/Molecular Massively Parallel Simulator, is a molecular dynamics simulator. LAMMPS has potentials for solid-state materials (metals, semiconductors) and soft matter (biomolecules, polymers) and coarse-grained or mesoscopic systems.

Did they explicitly state that they were using fix shake during minimization (or only during MD). The SHAKE algorithm is only derived for MD simulation time stepping and cannot be applied during minimization (applying constraints during minimization is a “hard” problem). christophe bayard alençonWebCommon problems — LAMMPS documentation. 11. Errors. 11.1. Common problems. 11.1. Common problems. If two LAMMPS runs do not produce the exact same answer on different machines or different numbers of processors, this is typically not a bug.
