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.

What can Seismo-VLAB do?

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

Installing Seismo-VLAB

Installation of Seismo-VLAB on Linux/MacOS/Windows is perform in two steps:

• The Pre-Process requires python3 and the following libraries:

  • Numpy
  • Scipy
  • Matplotlib
  • JSON

  These librarires can be installed using pip3 or standard Linux and Mac repositories.

• The Run-Process requires requires to download Eigen C++ library, MUMPS Library, and PETSc Library.

  • 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.inc file 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
