def horizontal_nodal_proxy(formdata, forcedata, *args, **kwargs):
"""RPC proxy for node-per-node calculation of horizontal equilibrium.
Parameters
----------
formdata : dict
The data dictionary of a :class:`FormDiagram`.
forcedata : dict
The data dictionary of a :class:`ForceDiagram`.
Additional Parameters
---------------------
alpha : int, optional
Weighting factor for computing target vectors for parallelisation
of corresponding edges of Form and ForceDiagram.
Default is `100` which means that the target vectors are equal to the
FormDiagram edges.
kmax : int, optional
Maximum number of iterartions.
Default is `100`.
display : bool, optional
Display all messages generated by the solver.
Default is `True`.
Returns
-------
tuple
0. The updated data dict of the FormDiagram.
1. The updated data dict of the ForceDiagram.
