    name: str
        A String specifying the load repository key.
    distributionType: SymbolicConstant
        A SymbolicConstant specifying how the body concentration flux is distributed spatially.

            A String specifying the load repository key.
        createStepName
            A String specifying the name of the step in which the load is created.

        magnitude
            A Float specifying the body concentration flux magnitude. **magnitude** is optional if
            **distributionType** = USER_DEFINED.
        field

        amplitude
            A String or the SymbolicConstant UNSET specifying the name of the amplitude reference.
