In recent years, computer-based research employing numerical methods has increased because it can reduce the cost and save time in analyzing a model. Nevertheless, each numerical model has a unique shape and set of characteristics, necessitating preliminary research on modeling techniques to obtain accurate results. The shape and number of the mesh elements are two of the essential characteristics that need to be taken into consideration. In this study, various mesh element types are evaluated to simulate the behavior of interlocking modular blocks under lateral loads, which can be used to represent actual conditions. Four types of modular block models are used to evaluate mesh arrangements with various types of connections. The simulation results indicate that the model with a hexahedral mesh provides more consistent data and performs analyses faster than the model with a tetrahedral mesh. By applying a hexahedral mesh, it will be more appropriate to discover the optimum value of the convergent mesh that reflects the actual conditions of the modular block. [ABSTRACT FROM AUTHOR]
