1.- Modify the 'makefile' file to put the name of the program in it.

2.- In the directory in which you have the code and the makefile, generate the 
executable program.

	instruction: make program_2D_square

3.- Execute the program. 

	instruction: ./program_2D_square

4.- Generate the .vtk files with the python code. 

	instruction: python Plot_square2D.py


NOTE: This code can be executed in serial.

1.- Modify the 'makefile' file to put the name of the program in it.

2.- In the directory in which you have the code and the makefile, generate the 
executable program. 

	instruction: make program_3D_cube

3.- Execute the program.

	instruction: ./program_3D_cube

4.- Generate the .vtk files with the python code. 

	instruction: python Plot_cube3D.py

NOTE: We recommend to run this code in parallel with at least 4 cores.

1.- Modify the 'makefile' file to put the name of the program in it.

2.- In the directory in which you have the code and the makefile, generate the 
executable program. 

	instruction: make program_3D_prostate

3.- Execute the program with the prostate geometry (namefile.dat).

	instruction: ./program_3D_prostate -iga_geometry namefile.dat

4.- Generate the .vtk files with the python code. 

	instruction: python Plot_prostate3D.py

NOTE: We recommend to run this code in parallel with at least 8 cores.
