oomph-lib: Global_Physical_Variables Namespace Reference

Namespace for phyical parameters. More...

Functions
void	prescribed_traction (const double &t, const Vector< double > &x, const Vector< double > &n, Vector< double > &traction)
	Traction applied on the fluid at the left (inflow) boundary.

void	load (const Vector< double > &xi, const Vector< double > &x, const Vector< double > &N, Vector< double > &load)
	Load function: Apply a constant external pressure to the wall. Note: This is the load without the fluid contribution! Fluid load gets added on by FSIWallElement.

Variables
double	Re =50.0
	Reynolds number.

double	ReSt =50.0
	Womersley = Reynolds times Strouhal.

double	P_up =0.0
	Default pressure on the left boundary.

double	H =1.0e-2
	Non-dimensional wall thickness. As in Jensen & Heil (2003) paper.

double	Sigma0 =1.0e3
	2nd Piola Kirchhoff pre-stress. As in Jensen & Heil (2003) paper.

double	P_ext =0.0
	External pressure.

double	Q =1.0e-5
	Fluid structure interaction parameter: Ratio of stresses used for non-dimensionalisation of fluid to solid stresses.

double	Lambda_sq =0.0
	Pseudo-solid mass density.

double	Nu =0.1
	Pseudo-solid Poisson ratio.
