Function Documentation

int MdtKeaMemoryRequired ( int * rows_in_partition, int num_partitions )

Utility function for calculating the size of the workspace needed by Kea.

This memory is passed into Kea in the MdtKeaParameters structure.

void MdtKeaStep ( MdtKeaConstraints constraints, MdtKeaBody * blist, MdtKeaTransformation * tlist, int num_bodies, MdtKeaParameters parameters )

Kea solver function.

Takes an array of bodies and a MdtKeaConstraints struct (which defines the constraints as defined above), as well as an array indicating which constraints are to be solved together as one partition. It solves each partition and evolves the system.

Parameters:

constraints	A MdtKeaConstraints struct containing constraint rows generated by MdtBcl functions.
blist	Array of MdtKeaBody structs to be simulated.
tlist	Array of MdtKeaTransformation structs that correspond to blist.
num_bodies	Number of bodies/transformations in blist/tlist
parameters	A MdtKeaParameters structure containing stepsize, memory pool etc.
