WHY YOU'LL LOVE IT

Why Choose PFC2D?

Maximize efficiency in granular material simulation with powerful and user-friendly tools in 2D, including the ability to run two instances simultaneously. Discover why PFC2D is the ideal choice:

  • Small-strain mechanics (particle/blocks remain fixed)

  • Large-strain mechanics (particle/blocks move with displacement)

  • Back-analyze failure and calibrate forward-prediction

  • Multiple, Simultaneous Failure-Mechanisms

  • Material Flow

  • Synthetic Rock Mass (SRM)

  • Bonded Particle Modeling (BPM) and Bonded Block Modeling (BPM) for fragmentation and fracturing

  • Service limit state (SLS) and ultimate limit states (ULS) based on displacements

  • User Defined Contact Models (UDC)

  • Surface Subsidence

  • Recovery and Dilution

  • Coupled ground-structure interaction (beams, cables, piles, shells, geotextiles, liners)

  • Commercial grade, discrete element model (DEM) simulator for free or bonded balls, clumps, rigid blocks, and walls

  • Options Included: Dynamics (Earthquakes, Blasting, Vibration), Thermal

  • PFC2D simplifies model construction to controlling particle size distribution and target porosity, practical and straightforward material property assignments, bonded assemblies (bricks) that may be rapidly replicated over the model domain, and domain boundaries to stop, destroy, or reflect particles or be periodic.

    Easily convert DXF or STL files into model geometry and geometry into walls to contain particles. Assign conveyor velocities to wall facets to simulate spinning drums or conveyor belts. Static or mobile particle inlets generate streams of balls, clumps, and/or rigid blocks into the model during cycling.

    Schemes for ball and rigid block packings are available to simplify stress installation. Clumps of particles can be easily generated from templates and bubble packing automatically creates clump templates for a CAD surface. The FISHTank provides a material-modeling support environment for calibrating and simulating lab tests. Extensive help documentation and Inline Help for command completion is available.

  • PFC2D utilizes multi-threading and optimized solutions for fast, responsive, and accurate simulations. Multi-threaded FISH and Python libraries provide extremely efficient model scripting when user customization is chosen.

    Users may also run two instances of PFC Suite on the same computer simultaneously, cutting down on overall time to solution for multiple models.

  • PFC2D offers robust DEM simulation capabilities to model particles, clumps of particles, and rigid blocks. Elements may be free or bonded together and may slide, rotate, move apart, or come together. Interface coupling between PFC3D particles and rigid blocks with FLAC3D zones, and domain bridging for dynamic modeling is possible. FLAC3D structural elements (for ground support) are available in PFC Suite.

    Convex rigid blocks can be used for simulating non-spherical objects and Bonded Block Models (BBMs). For jointed or blocky rock, there is a built-in statistical generator for Discrete Fracture Networks (DFNs); fractures can also be imported from Itasca and Fracman file formats. Advanced plotting tools, FISH scripting and Python integration provide unparalleled model control and customization, while statistical tools and data import options expand modeling possibilities.

  • PFC2D is general by design. Enjoy flexibility in your workflow to build and modify your models. Use FISH and/or Python scripting for model parameterization, custom visualizations, adding new physics, and/or model run control. PFC Suite includes 12 built-in contact models for joints in rock, creep, impact dynamics, magnetic interactions, adhesion, rigid bonded block modeling (BBM), and more. Create your own custom user-defined contact model via C++ and provided templates.

    PFC2D can be coupled to third-party Computation Fluid Dynamics (CFD) programs. Run PFC2D on both Windows and Ubuntu Linux operating systems. PFC2D licenses allows for two instances to run on the same computer simultaneously. Licenses are also portable between computers using a USB key or web license.

  • Flexibility is a hallmark of PFC2D, allowing users to adapt to a wide range of geotechnical challenges. This software offers customizable options and versatile modeling capabilities, making it suitable for various applications.

    Whether you’re simulating different material properties, applying varied boundary conditions, or integrating thermal analysis, PFC2D’s adaptability ensures you can address diverse geomechanical projects with precision and efficiency. Experience limitless possibilities in geotechnical analysis with PFC2D’s adaptable and versatile platform.

“The software [is] very stable and the software manual is very well-organized and clear. [Also], the software integration between PFC3D and FLAC3D makes it easier to create coupled finite difference and discrete element models than [ever] before.”
Chong Wei, PhD
"I have been using PFC2D/3D for the last 18 years as a research tool, and I have to congratulate you on version 5 of PFC. The interface/post processing is very helpful, the changes made to fish and also the commands now make it easier to use and still as powerful as ever."
Corné Coetzee, Associate Professor, Stellenbosch University
“PFC is simple to use and the examples provided explain and help a lot.”

MORE TO LOVE

Everything You Need And More Included:

  • Dynamics, specifically the Computational Fluid Dynamics (CFD) Module for PFC2D, allows for the solution of fluid-particle interaction problems. It employs a coarse-grid approach, enabling the connection of PFC2D with an external CFD solver of choice. This module facilitates two-way coupling, with information exchange between PFC2D and the fluid-flow solver. It assumes fluid elements are larger than PFC2D particles, and it can model various fluid-flow equations, including Navier-Stokes, potential flow, and Euler equations. The module provides methods for reading a fluid mesh, storing fluid properties, calculating porosity, and applying fluid-particle interaction forces during PFC2D cycling. It offers three illustrative examples, showcasing different coupling scenarios and applications.

  • The thermal module in PFC2D simulates transient heat conduction, thermally induced strains, and forces within materials composed of PFC particles. It offers both thermal-only and coupled thermal-mechanical analyses, with heat conduction occurring through active thermal contacts. Custom criteria can inhibit thermal contacts. The model can run independently or coupled with the mechanical model, considering thermal boundary conditions and bond breakages that modify heat conduction ability. This module is versatile for various heat-related analyses.
