Abstract

The 2.5D Finite Element Method is commonly used in geophysical applications where the goal is to solve a 3-dimensional problem by a set of 2-dimensional models. The key assumption in 2.5D Finite Element analysis is to approximate the medium to be translationally invariant along one of the coordinates. In this work, complimentary modules are developed to enhance the EIDORS [1] project by the 2.5D Finite Element technique based on the complete electrode model using the proper boundary condition. Furthermore, the efficiency of the method is discussed and the accuracy of the forward solution employing different number of 2-dimensional model is investigated.
