Global, Communicating and InfiniteMass flags

These flags are given during the creation process of the rigid body. They can be retrieved with RigidBody::isGlobal(), RigidBody::isCommunicating() and RigidBody::hasInfiniteMass().

The global flag decides if the rigid body is stored in the global body storage or in one of the block local body storages. If the body is stored in the global body storage it will receive a global system id. Infinitely large bodies like planes are always global.

The communicating flag decides if the body takes part in the synchronization process, e.g. it spawns shadow copies and updates already existent shadow copies. Bodies which do not move throughout the simulation can be made non communicating.

Attention
There will be no shadow copies of non communicating bodies even if they overlap a subdomain boundary. To overcome this drawback you can set syncNonCommunicatingBodies to true once in your sync call (syncNextNeighbors() or syncShadowOwners()).

The infiniteMass flag decides if the body is "considered" by the collision resolution system. It still influences other rigid bodies but will not be moved itself. Rigid bodies with the infiniteMass flag set can still have a static velocity and will move accordingly.

"Object with id: xxx not found in shadowStorage! Cannot transfer ownership!"

Most likely one of your bodies got too fast. The process of migrating a rigid body to a new process is:

  1. overlap new subdomain
  2. sync
  3. move center of mass into the new subdomain
  4. sync

If a rigid body gets fast enough to move its center of mass into a new subdomain without first creating a shadow copy you will receive that error message.

Contacts Involving Unions

Collision detection for unions is done by colliding each of its subbodies separately. The contacts generated involves the subbodies. With this approach you can use different material parameters for every subbody and the solver component can retrieve the material of every collision partner by retrieving the material of Contact::getBody1(), Contact::getBody2().

Attention
To get the correct mass and inertia of a union during collision resolution you should call RigidBody::getTopSuperBody() and then RigidBody::getMass() (RigidBody::getInertia()) using the returned rigid body.

How can I dynamically switch between sync calls?

You can bind the function to a std::function and call this one.

std::function<void(void)> syncCallWithoutTT;
{
syncCallWithoutTT = std::bind( pe::syncNextNeighbors<BodyTuple>, std::ref(*forest), storageID, static_cast<WcTimingTree*>(nullptr), real_c(0.0), false );
} else
{
syncCallWithoutTT = std::bind( pe::syncShadowOwners<BodyTuple>, std::ref(*forest), storageID, static_cast<WcTimingTree*>(nullptr), real_c(0.0), false );
}

Template Parameters
BodyTypeTuplestd::tuple of all geometries used throughout the simulation

Each geometry has a unique type id which is used to identify the geometry. These type ids have to be set at the start of the simulation using this function.

Note
You have to call this function on all processes identically.

The template parameter is a std::tuple of geometries used during the simulation. Since the tuple is used often a typedef is used.

typedef std::tuple<Box, Capsule, Plane, Sphere, UnionT> BodyTypeTuple ;
