Welcome to Hermes3D!
====================

Hermes3D is a C++ library for rapid prototyping of adaptive hp-FEM 
solvers for 3D problems. The usage of Hermes3D is very similar to 
Hermes2D, and thus it is recommend to get familiar with Hermes2D 
first. Also the User Documentation of Hermes3D concentrates on things 
that are different from Hermes2D.

Download and Installation
=========================

Installation instructions for Linux, Mac OS X and Windows Cygwin 
can be found in the Sphinx documentation at 
http://hpfem.org/hermes3d/doc/index.html. 


Documentation
=============

Generating and Viewing User Documentation Offline (Linux)
---------------------------------------------------------

Source files of the (Sphinx) user documentation are in the
directory doc/. In order to compile the user documentation, 
you need to install Sphinx. Then follow these steps:

cd doc
make html
firefox _build/html 

Generating and Viewing Developer Documentation Offline (Linux)
--------------------------------------------------------------

Source files of the (Doxygen) developer documentation are
in the directory doc.cpp/. In order to build them you need
to install Doxygen. Then do:

cd doc.cpp/
doxygen hermes3d.lib-real.doxyfile
doxygen hermes3d.lib-cplx.doxyfile

This will generate documentation for the real and complex
version of the library, respectively. To view the docs, 
type

firefox h3d-real/html/index.html
firefox h3d-cplx/html/index.html


Compilation
===========

$ cmake .
$ make

If you have cmake text-based UI installed, you can do:

$ ccmake .
  press C  
  customize your build
  press C
  press G
$ make

Hermes3D build configuration scripts will look for required libraries on default include and system
paths. If you packages are installed elsewhere, you need to specify their paths. Consult either
online documetation (http://hpfem.org/hermes3d/doc/install.html) or cmake/FindXYX.cmake files for
exact names. These values have to be put into CMake.var file located in your build directory. 

Intel C Compiler
================

To use Intel C compiler

$ export CC=/path/to/icc
$ export CXX=/path/to/icpc
$ cmake .
$ make

NOTE: version 10.0.026 did not work for me (some compatibility issues with STL), 10.1.022 works ok


Tests
=====

To enable tests, say 'set(WITH_TESTS YES)' in your CMake.vars.
To run the tests, type:

$ make test

To run quick tests, type:

$ make test-quick

Note: To run developer tests, say 'set(DEV_TESTS YES)' in CMake.vars. This is needed to run only if
the lowest internals are changed. Developers test suite includes hundreds of tests for hanging
nodes. These will run for several hours in case of H1 space, Hcurl ones take days. These test do not
have to be run every time.


Examples
========

To build examples, type (supposed you enabled examples during the configuration):

$ make examples

To get output files that can be viewed in a visualizer, you need to say:

set(OUTPUT_DIR /path/where/the/files/will/be/stored)

To view the files:
# gmsh my-file.gmsh (for gmsh)
# paraview --data=my-file.vtk (for VTK)


Debugging
=========

If you need to debug the build, use:

cmake -DCMAKE_VERBOSE_MAKEFILE=ON .

Then the make will print the exact commands that are executed.
