1. Brief Introduction

Viscous-Spring Boundary and Equivalent Node Load Application is a program that automatically applies viscoelastic boundary conditions and inputs seismic wave with equivalent nodal load. It has a graphical user interface that is easy to use and understand, and data visualizations through the program are made possible thanks to the advanced plotting capability of MATLAB. And the program VBEA is only for the model of two-dimensional homogeneous media with vertically incident SV seismic waves.

2. Installation

VBEA is installation-free, but because it is written in MATLAB, the users need to install MCR (MATLAB Compiler Runtime) first. MCR installer can be downloaded from the MathWorks website[1]. After installing MCR, the VBEA.exe can be launched directly. Please note that the first launching of the program takes one to two minutes. The screenshot of the main panel of Program for VBEA is shown in Fig. 1.
