1. setting the domain size for the problem to be solved

domain_size = 2

1. 1. ATTENTION: here the order is important

1. including kratos path

kratos_libs_path = '../../../../libs' ##kratos_root/libs

1. kratos_libs_path = 'C:/kratosR1/libs' ##kratos_root/libs

kratos_applications_path = '../../../../applications/' ##kratos_root/applications

import sys

sys.path.append(kratos_libs_path)

sys.path.append(kratos_applications_path)

1. importing Kratos main library

from Kratos import *

kernel = Kernel() #defining kernel

1. importing applications

import applications_interface

applications_interface.Import_IncompressibleFluidApplication = True

applications_interface.ImportApplications(kernel, kratos_applications_path)

1. 1. from now on the order is not anymore crucial

print model_part

1. the buffer size should be set up here after the mesh is read for the first time

model_part.SetBufferSize(3)

1. 1. add Degrees of Freedom to all of the nodes

incompressible_fluid_solver.AddDofs(model_part)

1. creating a fluid solver object
