Software: PFC3D

Examples

		PFC3D Pressure Boundary Condition A pressure boundary condition can be applied to the surface of a PFC3D model via the shining-lamp algorithm, which was developed to support rock-cutting simulations in which a cutter is moved at a specified velocity and depth of cut across the surface of a PFC3D material, while monitoring forces on the cutter and damage in the material. Application of the shining-lamp algorithm is not limited to rock-cutting simulations — e.g., it could also be used to apply confinement to a PFC3D material during the simulation of a confined-compression test. The shining-lamp algorithm is described in the accompanying technical memo linked below. [Technical Memorandum (PDF: 3.4MB)]
		Molecular dynamics with PFC Molecular dynamics (MD) simulation involves solving the classical many-body problem in contexts relevant to the study of matter at the atomistic level. The introductory section first defines MD simulation, and then situates the PFC programs within the MD framework. The second section presents the Lennard-Jones potential. Then, the PFC implementation of atomic interactions via the Lennard-Jones potential is described in Section 3. The PFC implementation supports any nuMBer of atom types with different Lennard-Jones parameters for each coMBination of atom-atom interaction. Extensions of the PFC implementation to support the TIP4P water molecule are presented in Section 4, and limitations of the PFC implementation are discussed in Section 5.

		Quiet Boundaries and Seismic Wave Input There is no built-in operation in PFC3D that corresponds to FLAC’s quiet boundary and input history logic, but a similar formulation may be provided with user-written FISH functions. [documentation (PDF: 1.1MB)]
		CAD Data Import An illustration of complex geometry import into PFC3D from Computer-Aided Design (CAD) data. (This excerpt from the PFC3D Manual was not included with the code release. The data files for it appear in the excerpt and are included in the the latest update to PFC3D.) [Manual Excerpt (PDF: .985MB)]
