IFEM is an object-oriented toolbox for implementing isogeometric finite element
solvers for linear and nonlinear partial differential equations.
The toolbox is developed through the ICADA project at SINTEF ICT, Trondheim.
The toolbox was developed through the ICADA project at SINTEF Digital.
The purpose of this code is to serve as a common base for isogeometric
PDE-simulators, using splines and NURBS as basis functions in the finite element
formulations. The toolbox contains methods for doing linear and non-linear,

The simulation toolbox is organized into a set of modules,

The top-level driver is organized in the class `SIMbase` and its sub-classes.
These classes have methods for reading model data from an input file,
to assemble the linearized algebraic system of equations resulting from the
finite element discretization, and to solve that system.
It also contains methods for writing a VTF-file with results.
Problem-specific drivers and main programs are found in the sub-folder Apps.
The core of the finite element implementation is contained in the class
ASMbase and its sub-classes, which have methods for evaluating the element

A number of things need to be set up properly to compile the IFEM library.
First, we will add inhouse dependencies by a secondary repository.
1. Add the IFEM repository at https://launchpad.net/~ifem/ (follow the instructions on site)

### Getting the code
This is done by first navigating to the folder in which you want IFEM installed and typing
Navigate to the folder in which you want the IFEM source installed and type
git clone https://github.com/OPM/IFEM
### Compiling the code
To compile, first navigate to the root catalogue of IFEM, here denoted by `<IFEM root>`.
Navigate to the root folder of IFEM source, here denoted by `<IFEM root>`. Then
1. `cd <IFEM root>`
2. `mkdir Debug`
3. `cd Debug`
4. **[optional]** specify which submodules you have available in `<IFEM root>/cmake/Modules/IFEMoptions.cmake`
5. `cmake -DCMAKE_BUILD_TYPE=Debug ..`
6. `make `
1. `mkdir Debug`
2. `cd Debug`
3. `cmake .. -DCMAKE_BUILD_TYPE=Debug [<IFEM-options>]`
4. `make `
this will compile the library.
Change all instances of `Debug` with `Release` to drop debug-symbols, but get faster running code.
where `<IFEM-options>` is an optional list of sub-modules
you may choose to activate or deactivate in your build.
See the file `<IFEM root>/cmake/Modules/IFEMOptions.cmake` for a complete list
of available options and their default setting.
This will compile the libraries which can be found in the `Debug/lib`sub-folder.
Change all instances of `Debug` with `Release` to drop debug-symbols,
and get a faster running code.
### Testing the code
IFEM is using cmake test system. To compile run all regression- and unit-tests, navigate to your build
