JGR-Interactions between gas slug ascent and exchange flow in the conduit of persistently active volcanoes Including the code used in Qin et al (2021): Interactions between gas slug ascent and exchange flow in the conduit of persistently active volcanoes. This repository includes the codes used to simulate the ascenting slug in exchange flow. Code Folder: The code folder includes the codes used to reproduce the analogue experiment, which is developed using FORTRAN. Specifics on the development of the model and implementation are included in Qin et al (2021). To run this code, the reader should copy the whole folder into a single directory in his/her local computer or a server. • UMFPACK Library Our codes use UMF library to solve the large sparse matrix. The UMFPACK library, written by Timothy Davis, is part of the SuiteSparse package, which is available from http://www.cise.ufl.edu/research/sparse/ . The library files used by the authors have been included in the CODE/lib. To run a code, save all library files and the code in a same directory. However, these library files might not work in readers' local computer. Therefore, we suggest the readers to download and install their own library in their local computer. The UMFPACK use guide is in: https://fossies.org/linux/SuiteSparse/UMFPACK/Doc/UMFPACK_UserGuide.pdf. • Input Our codes are suitable for a wide range of parameters. The input of geometry and properties of fluids can be typed manually by readers in the “data input” area at the beginning of each code. • Output We output the properties of multiphase, velocity and pressure profile frequently. Besides, in order to monitor the progress of the simulations, we output a runtime text file that prints residuals of the mechanical solvers and the position of the gas slug. • Run To begin running a code, readers need to assign the name of the code in code/comp_2d2, then type and run “./comp_2d2” in a linux terminal to compile the fortran code executable, which will be named "a.out". After the executable file was formed, type and run “./a.out”. The run time depends on the spatial and temporal resolution. Simulation output files will be created in the same directory as the code is run. |
