 The one-dimensional equations for the flow of a Newtonian, incompressible fluid in a deforming, elastic domain consist of the continuity equation, a single axial momentum balance equation, a constitutive equation, and suitable initial and boundary conditions. 
 
-## Installation

-### Prerequisites
-
-The following software is required:
-
-- Sphinx  (HTML Manual)
-- SWIG Interface generator (Python Interface)
-- MPI (mpi4py is used for running parameteric simulations from python)
-- SuperLU_MT (if you would like to use this sparse solver)

-Out-of-source is the suggested build modality. To do this, first create a build folder (for example "OneDBin") as a sibling of the main source code folder (probably "svOneDSolver")

-mkdir svOneDSolver_build

 There are three supported usages for the generated executable. 
 * The quotations around the input args are optional
 * Input file paths can be specified as a local file name or an absolute path
