Forward Modeling of Frequency-domain Helicopter-borne Electromagnetic Data using an Improved Finite Difference Method

Saeed Nazari; Alireza Arab Amiri; Abolghasem Kamkar Rouhani; Fereydoun Sharifi

Volume 13, Issue 4 , October 2022, , Pages 1067-1089


  In this work, we simulate the frequency-domain helicopter-borne electromagnetic (HEM) data over the two-dimensional (2D) and three-dimensional (3D) earth models. In order to achieve this aim, the vector Helmholtz equation is used to avoid the convergence problems in Maxwell’s equations, and the ...  Read More

Effects of geometrical and geomechanical properties on slope stability of open-pit mines using 2D and 3D finite difference methods

H. Zebarjadi Dana; R. Khaloo Kakaie; R. Rafiee; A.R. Yarahmadi Bafghi

Volume 9, Issue 4 , October 2018, , Pages 941-957


  Slope stability analysis is one of the most important problems in mining and geotechnical engineering. Ignoring the importance of these problems can lead to significant losses. Selecting an appropriate method to analyze the slope stability requires a proper understanding of how different factors influence ...  Read More

A boundary element/finite difference analysis of subsidence phenomenon due to underground structures

S. E. Mirsalari; M. Fatehi Marji; J. Gholamnejad; M. Najafi

Volume 8, Issue 2 , April 2017, , Pages 237-253


  Analysis of the stresses, displacements, and horizontal strains of the ground subsidence due to underground excavation in rocks can be accomplished by means of a hybridized higher order indirect boundary element/finite difference (BE/FD) formulation. A semi-infinite displacement discontinuity field is ...  Read More
