so that the input is now dictionary rather than list of dictionaries which
provides support for dictionary substitutions within the motionSolver
sub-dictionaries and also simplifies lookup of specific motionSolvers within the
list. For example the dynamicMeshDict for the floatingObject case with a second
floating object would be:
mover
{
type motionSolver;
libs ("libfvMeshMovers.so" "librigidBodyMeshMotion.so");
motionSolver motionSolverList;
solvers
{
floatingObject
{
motionSolver rigidBodyMotion;
report on;
solver
{
type Newmark;
}
accelerationRelaxation 0.7;
bodies
{
floatingObject
{
type cuboid;
parent root;
// Cuboid dimensions
Lx 0.3;
Ly 0.2;
Lz 0.5;
// Density of the cuboid
rho 500;
// Cuboid mass
mass #calc "$rho*$Lx*$Ly*$Lz";
L ($Lx $Ly $Lz);
centreOfMass (0 0 0.25);
transform (1 0 0 0 1 0 0 0 1) (0.5 0.45 0.1);
joint

type composite;
joints
(

type Py;

patches (floatingObject);
