  • Modeling Flow in Porous Media with Darcy’s Law
    Modeling Flow in Porous Media with Darcy’s Law This example demonstrates using the Python scripting capability and the PFC CFD module to model low Reynolds number porous flow in a granular material
  • Effect mechanism of seepage force on the hydraulic fracture propagation
    During fluid displacement, the flow rates at the inlet and outlet are monitored, and the permeability is calculated using Darcy's law As shown in Fig 3 c, when the inlet and outlet rates are stable and close, the flow reaches a steady state
  • Numerical modelling of structural controls on fluid flow and . . .
    A discrete deformation model using PFC2D and a correlating continuum deformation-fluid flow model using FLAC2D, both two dimensional, have been constructed to explore this question
  • PFC Overview — PFC 6. 0 documentation - Itasca International
    The PFC programs (PFC2D and PFC3D) provide a general purpose, distinct-element modeling framework that includes both a computational engine and a graphical user interface A particular instance of the distinct-element model is referred to as a PFC model
  • Simulation of hydraulic fracturing and Darcy fluid flow in a porous . . .
    Studying fluid penetration of the rock matrix during fracture propagation is one of the most difficult technical challenges of hydraulic fracture engineering To deal with this issue, a coupled hydraulic-mechanical model was performed to simulate fracture propagation during hydraulic fracturing
  • PFC双向流固耦合 - 哔哩哔哩
    PFC中流固耦合目前有两种方法，一种是使用PFC自带的CFD模块，这种方法建模简单计算快，但是只考虑了流体对颗粒的影响，没能考虑颗粒对流体的影响，所以一般称之为单向耦合。 今天介绍一种利用Python的Fipy库在PFC内实现双向流固耦合，即既考虑流体对颗粒的影响也考虑颗粒对流体的影响。 本文使用的为PFC自带的darcy py 案例进行修改。 首先看几张效果图 颗粒位移云图 流体流速场 流体网格 颗粒位移场 下面来看具体的实现过程 由于Fipy库的函数只能生成方形区域，而在实际应用中区域往往是不规则的，Fipy是支持从外部导入网格，但是却只支持导入Gmsh的网格。 当我们满心欢喜的把Gmsh网格导入Fipy的时候，会遇见报错，提示Gmsh版本必须大于等于2 0。
