Seismo-VLAB (a.k.a SVL) is a simple, fast, and extendable C++ finite element software designed to optimize meso-scale simulations of linear and nonlinear wave-propagation and soil-structure interaction. SVL is intended not only to be used by researchers in structural and geothecnical engineering, but also in industries, laboratories, universities, etc.
With Seismo-VLAB you can solve:
- Linear and nonlinear wave propagation problems in shallow crust
- Linear and nonlinear soil-structure interaction problems
- Standard structural-mechanics linear and nonlinear dynamic problems
Visit our gallery to see some examples of simulations using SVL.
Installation of Seismo-VLAB on Linux/MacOS/Windows is perform in two steps:
-
The Pre-Process requires
python3and the following libraries:These librarires can be installed using
pip3or standard Linux and Mac repositories. -
The Run-Process requires requires to download
EigenC++ library,MUMPSLibrary, andPETScLibrary.- The Eigen C++ library can be downloaded from this website. This package needs to be unzip and its content move to
/usr/include/eigen. - The MUMPS library can be downloaded from this website. This package needs to be unzip and compiled at
/usr/include/mumps. - The Pestc Library can be downloaded at this website. This package needs to be unzip and compiled at
/usr/include/petsc.
Assuming the previous libraries are successfully installed, then modify the
Makefile.incfile such the previous path point to the right libraries:EIGEN_DIR = /usr/include/eigen PETSC_DIR = /usr/include/petsc MUMPS_DIR = /usr/include/mumps
Also, make sure that libraries such as: libscalapack-openmpi, libblacs-openmpi, liblapack, libblas, and libparmetis, libmetis, libptscotch, libptscotcherr are also installed.
Finally, write in terminal:
make -s DEBUG=False

abstract = {We present Seismo-VLAB (SVL), a new open-source, object-oriented finite element software designed to optimize meso-scale simulations in the context of structural and geotechnical engineering. To this end, state-of-the-art tools and parallel computing capabilities required for efficient modeling of soil–structure interaction and wave propagation in heterogeneous half-spaces are included. For example, perfectly matched layer, domain reduction method, dynamic nonlinear solvers, cutting edge parallel linear system solvers, domain decomposition method, and a series of plasticity models are some of the features available in SVL. In this work, we present the numerical implementation and software structure so enthusiastic developers can contribute to this open-source project and showcase some software capabilities using an illustrative example.}

ABSTRACT = {In the fields of structural and geotechnical engineering, improving the understanding of soil–structure interaction (SSI) effects is critical for earthquake-resistant design. Engineers and practitioners often resort to finite element (FE) software to advance this objective. Unfortunately, the availability of software equipped with boundary representation for absorbing scattered waves and ensuring consistent input ground motion prescriptions, which is necessary for accurately representing SSI effects, is currently limited. To address such limitations, the authors developed Seismo-VLAB (SVL v1.0-stable) an open-source software designed to perform SSI simulations. The methodology considers the integration of advanced techniques, including the domain decomposition method (DDM), perfectly matched layers (PMLs), and domain reduction method (DRM), in addition to parallel computing capabilities to accelerate the solution of large-scale problems. In this work, the authors provide a detailed description of the implementation for addressing SSI modeling, validate some of the SVL’s features needed for such purpose, and demonstrate that the coupled DRM–PML technique is a necessary condition for accurately solving SSI problems. It is expected that SVL provides a significant contribution to the SSI research community, offering a self-contained and versatile alternative. The software’s practical application in analyzing SSI and directionality effects on 3D structures under seismic loading demonstrates its capability to model real-world earthquake responses in structural engineering.},
