Member Function Documentation

void assemble ( double *  rhs,
double *  lhs,
double *  flv 
)

Function assembles vector of right hand side with respect of left hand side node forces cause by the attained displacements.

Parameters:
rhs - right hand side vector
lhs - left hand side
flv - array of load vector caused by forces only

void assemble ( long  lcid,
double *  rhs,
double *  flv,
long  n,
double  t 
)

Function assembles vector of right hand side. It is created by prescribed displacements, forces, moments, eigenstrains, etc. In case that the flv is not NULL, vector of load caused by forces only is stored in flv.

Parameters:
lcid - load case id
rhs - right hand side vector
flv - array of load vector caused by forces only
n - the number of DOFs in problem
t - actual time

double get_pd ( double  time,
long  dof 
)

Function returns prescribed displacement for the given time and dof.

Parameters:
time - actual time
dof - DOF id
Returns:
The function returns prescribed displacement.
