rheolef 6.7-3build1 (i386 binary) in ubuntu bionic

 Rheolef is a computer environment that serves as a convenient
 laboratory for computations in applied mathematics involving finite
 element-like methods. It provides a set of commands and C++ algorithms
 and containers.
 .
 Most basically, containers cover the classic graph data structure for
 sparse matrix formats and finite element meshes. At a higher level of
 abstraction, they can handle approximate finite element spaces, discrete
 fields. Flexible and powerful expressions are used to specify bilinear forms.
 .
 Current applications include:
  * massively distributed memory finite element environment, based on MPI;
  * Poisson problems in d=1,2 and 3 dimension with high order Lagrange elements,
    up to fifth order;
  * linear elasticity, including incompressible and nearly incompressible
    elasticity;
  * Stokes problems in d=2 or 3 dimension, with P2-P1 or P1 bubble-P1 elements;
  * characteristic method for convection-diffusion, time-dependent
    problems and Navier-Stokes equations;
  * nonlinear problems with either fixed-point algorithms or a provided generic
    damped Newton solver;
  * auto-adaptive mesh approaches;
  * axisymmetric problems;
  * multi-regions and variable coefficient problems.
 .
 This package provides the rheolef commands. These support input and
 output in various file formats for mesh-generators and numerical data
 visualization systems such as MayaVi, Paraview, and gnuplot.
