within the North China Craton by fitting the real MT data collected there. Finally, we establish the 3-D lithospheric resistivity model for the Proterozoic Wutai-Hengshan Mts. Then, the reliability of this procedure is certificated by 1-D, 2-D and 3-D and anisotropic forward modeling tests. The calculated responses include the surface electric and magnetic field components, impedance components, magnetic transfer functions and phase tensors.
In order to improve the discretization technique of computing area, we use the combination of Matlab and COMSOL Multiphysics to establish a general procedure for calculating the MT responses for arbitrary resistivity models. Using the adaptive unstructured grid, the calculation is much faster. In addition, its AC/DC and RF module can be used to easily calculate the electromagnetic responses of complex geological structures. It achieves highly accurate numerical simulations with high computational performance and outstanding multi-field bi-directional coupling analysis capability. COMSOL Multiphysics is a cross-platform finite element analysis, solver and multiphysics full-coupling simulation software. However, the complexity of mesh gridding and limitation of computer capacity has been affecting its application. By contrast, the finite element method is more accurate in calculating complex and irregular 3-D region and has lower requirement of function smoothness. But its structured mesh gridding cannot be well adapted for the conditions with arbitrary topography or complex tectonic structures.

The full functionality of the interface was demonstrated to model transport processes, governed by extended Nernst-Plank equation, in Class H Portland cement samples in high pressure and temperature autoclaves simulating systems that are used to store captured carbon dioxide (CO2) in geological reservoirs. Benchmark comparisons show that the developed interface can be used to predict a variety of reactive-transport processes accurately. cement) using GEMS thermodynamic database formats.

COMSOL 5.3 CHEESE MODEL SOFTWARE
The two standalone software packages are managed from the interface that uses a non-iterative operator splitting technique to couple the transport ( COMSOL) and reaction (GEMS) processes. BurkanĪn interface was developed between COMSOL MultiphysicsTM finite element analysis software and (geo)chemical modeling platform, GEMS, for the reactive-transport modeling of (geo)chemical processes in variably saturated porous media. Overall, both software packages provided the ability to solve multiphysics phenomena accurately.Ī COMSOL-GEMS interface for modeling coupled reactive-transport geochemical processesĪzad, Vahid Jafari Li, Chang Verba, Circe Ideker, Jason H. COMSOL provided a flexible model setup whereas ANSYS required coupling incompatible elements to transfer load between electromagnetic, fluid flow, and heat transport modules. Prediction of power Loss by both models was in close agreement (5-13% variation) and the predicted temperature profiles were similar. Comparison of the results from the COMSOL model with the results from a pre-developed and validated ANSYS model ensured accuracy of the COMSOL model. Numerical models were developed to simulate temperature profiles in Newtonian fluids during continuous flow microwave heating by one way coupling electromagnetism, fluid flow, and heat transport in ANSYS 8.0 and COMSOL Multiphysics v3.4.
