Detailed Description
NodalLoads are loads acting on Nodes. The public methods are all declared as virtual to allow subclasses to be introduced for the provision of time varying loads. Each NodalLoad object is associated with a single Node object and has a Vector object corresponding to the load acting on this Node object as a result of the NodalLoad. \

NodalLoad::NodalLoad (
|
int classTag )
|
|
|
|
To create a NodalLoad object with tag {tag} acting on Node {node} with a reference load given by {load}. {tag} and {LOAD\_TAG\_NodalLoad} (defined in 
classTags.h\form#24)are passed to the Load constructor. A new vector object is created using the vector {load} as the argument. (THIS MAY CHANGE - may associate the load Vector with {load}, allowing identical loads on diff nodes to be created without the need for each to have its own vector) If no enough memory is available an error message is printed and the program terminates. The boolean {isLoadConstant} is used to indicate whether the value of the load applies to the Node is independent of the load factor.

NodalLoad::NodalLoad (
|
int tag,
|
|
int node,
|
|
int classTag )
|
|
|
|
Provided for subclasses, which may which to provide the abstraction of time varying nodal loads. The integers {tag} and {classTag} are passed to the Load constructor.

NodalLoad::NodalLoad (
|
int tag,
|
|
int node,
|
|
const Vector & load,
|
|
bool isLoadConstant = false )
|
|
|
|
Provided so that a FEM\_ObjectBroker can construct an object. 
and {classTag} are passed to the Load classes constructor. The data for the object is filled in when {recvSelf()} is invoked on the object.

NodalLoad::~NodalLoad (
|
)
|
|
|
|
If a Vector for the load was constructed, the destructor invokes delete on this Vector object.

To it's associated Node it invokes {addUnbalancedLoad()} with it's copy of the Vector object {load} and a factor of {loadFactor} if {isLoadConstant} was specified as {false} in the constructor or 
if it was specified as {true}. Warning messages are printed, if no Domain has been associated with the NodalLoad object or no Node with a tag {node} exists in the Domain. For efficiency reasons, the NodalLoad object keeps a pointer to it's associated Node object. The time {timeStep} has no influence on the load added.

The object first determines its database tag. It then invokes receives an ID object from the Channel containing it's tag, {node} and size of load Vector. If size of {load} is not
it then receives it's copy of the {load} Vector. Returns
if successful, a negative number if the Channel failed to receive the data.

Determines its database tag. The object then sends it's tag, {node} and size of load Vector to the Channel in an ID object. Then, if {load} is not NULL, it sends it's copy of the {load} Vector. Returns
if successful, a negative number if the Channel failed to send the data.
