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.

本团队研发了一套用于模拟控制天然气水合物分解诱导变形的非线性方程组的THMC求解器。控制方程采用有限体积法对流体进行离散化处理，而地质力学方面则采用有限元法。对于水合物承载介质的弹性属性计算，采用了广义有效介质模型。非线性与线性求解器均使用了PETSc库中的程序。在本数据集中，我们提供了用于解决该问题的原始计算机代码以及相应的Readme文件。
