This chapter gives some information to get a feeling for the internal structur
of the program Of course, it cannot mention all details. Furthermore
for a better understanding it is necessary o read al header and c-files of
K ARD OS very carefully.
5.1 Defining a time problem
To include all data of a initial boundary value problem two new data struc
ures are added.
struct timeProblem
char *name;
int (*Parabolic)(...);
int (*Laplace)(...);
int (*onvection)(...);
int (*elmholtz)(...);
int (*ource)(...);
int (*Jacobian)(...);
real (*InitialFunc)(...);
int (*auchy)(...);
int (*irichlet)(...);
int (*ol)(...);
struct timeProblemType
char *name;
int maxNoOfTimeProblems;
int noOfEquations;
The access to these srucures is realized by he pointers
timeProblem *actTimeProblem, *timeProblems;
timeProblemType *theTimeProblem;
Furthermore, there are some functions t announc ertain problms within
he program
int etTimeProblem(char *name, char **varames
int *Parabolic,
