This section presents how Seismo-VLAB can be installed in your local machine. Although we strongly recommend SVL to be installed in Linux or Unix environment, we provide a simple way to minimize Microsoft Windows (troubleshooting) issues. A detailed explanation on how to install SVL is provided in the following sections:

Once Pre-Analysis python libraries are installed, we recommend to export the SVL python path as follows:

export PYTHONPATH="/path/to/SeismoVLAB/01-Pre_Process"

The later will allow the user to import SVL Pre-Analysis in any Python script as a normal python module:

from Core import SeismoVLAB as SVL

The user can then verify the proper SVL Run-Analysis installation by executing in a terminal:

/path/to/SVL/02-Run_Process/SeismoVLAB.exe --help

The following message should be printed on the screen:

 COMMAND LINE FLAGS TO PROVIDE:                                  
     -dir  : Location of the working directory.                  
     -file : Name of the SeismoVLAB input file to be loaded.

Finally, a serial/parallel execution of Seismo-VLAB is performed in the following manner:

mpirun -np n /path/to/SeismoVLAB.exe -dir '/path/to/simulation/directory' -file 'model.#.$.json'

Note: the flag -np = n specifies that the number of processors are n. This requires the mesh and simulation files to be partitioned in such number of files. The .$. token represents a number that internally is replaced by the processor number, and .#. represents the load combination identifier (defined by the user) that is being solver.
