Fluid-Mechanical Interaction
This section contains information regarding the modeling of fluid in 3DEC. This includes theory and practical considerations for modeling flow through blocks (“Matrix Fluid Flow), flow along fractures (“Joint Fluid Flow”), and flow of proppant (“Proppant”). In each section, examples and verification problems are presented.
Properties and units used in fluid flow analyses are given in “Fluid Flow Properties and Units”. Commands and FISH functions related to fluid flow modeling are …
