Coupled THMC modeling of dissociation induced deformation of gas hydrate bearing media

We have developed a THMC solver to simulate the non-linear equations governing describing gas hydrate dissociation induced deformation. The governing equations are discretized using Finite Volume method for flow and Finite Element method for geomechanics. Generalized effective medium model is used for computing the elastic properties of the hydrate bearing media. PETSc routines are used for non-linear and and linear solvers. In this dataset, we have provided the original computer code used for solving the problem as well as a Readme file.

本研究开发了一款THMC（热-水-力学-化学）求解器，用于模拟控制天然气水合物分解诱发变形的非线性方程组。其中，流动控制方程采用有限体积法（Finite Volume Method）离散，岩土力学控制方程则采用有限元法（Finite Element Method）离散。本研究采用广义有效介质模型（Generalized Effective Medium Model）计算含天然气水合物介质的弹性特性，并借助PETSc程序库实现非线性与线性求解器功能。本数据集包含了用于求解该问题的原始计算机代码以及一份Readme文件。
