Function Documentation

◆ condense_check_flag()

static int condense_check_flag ( void *  flagvalue,
char *  funcname,
int  opt 
)
static

Check the return value from a SUNDIALS call.

  • opt == 0 means SUNDIALS function allocates memory so check if flagvalue is not a NULL pointer.
  • opt == 1 means SUNDIALS function returns a flag so check if the int pointed to by flagvalue has flag >= 0.
  • opt == 2 means function allocates memory so check if flagvalue is not a NULL pointer.
Parameters
flagvalueA pointer to check (either for NULL, or as an int pointer giving the flag value).
funcnameA string giving the function name returning this result code.
optA flag indicating the type of check to perform.
Returns
A result code (0 is success).

Definition at line 208 of file condense_solver.c.

◆ condense_jac_solve_f()

void condense_jac_solve_f ( int  neq,
double  t,
double *  ycur_f,
double *  fcur_f,
double *  b_f,
double  gamma 
)

◆ condense_solver()

int condense_solver ( int  neq,
double *  x_f,
double *  abstol_f,
double  reltol_f,
double  t_initial_f,
double  t_final_f 
)

Call the ODE solver.

Parameters
neqThe number of equations.
x_fA pointer to a vector of neq variables, giving the initial state vector on entry and the final state vector on exit.
abstol_fA pointer to a vector of neq variables, giving the absolute error tolerance for the corresponding state vector component.
reltol_fThe scalar relative tolerance.
t_initial_fThe initial time (s).
t_final_fThe final time (s).
Returns
A result code (0 is success).
