% CHPOINT.REAC
%--------------------------------------------------------------------------
% Computation of the reaction forces.

%--------------------------------------------------------------------------
% Syntax
%--------------------------------------------------------------------------
[REA_I,REA_II,CU_I,CU_II] = CHPOINT.REAC(CL1,CHP1)

%--------------------------------------------------------------------------
% Description
%--------------------------------------------------------------------------
% The REAC static method of the CHPOINT class is used to compute the
% reaction forces.

%--------------------------------------------------------------------------
% Input arguments
%--------------------------------------------------------------------------
% CL1     : MATRICE object describing the boundary condition
% CHP1    : CHPOINT object describing the displacement field

%--------------------------------------------------------------------------
% Output arguments
%--------------------------------------------------------------------------
% REA_I   : CHPOINT object describing the reaction forces associated with
%           the Lagrange multiplier of type I
% REA_II  : CHPOINT object describing the reaction forces associated with
%           the Lagrange multiplier of type II
% CU_I    : CHPOINT object describing the degrees of freedom whose the
%           value should be prescribed - related to Lagrange multiplier of
%           type I
% CU_II   : CHPOINT object describing the degrees of freedom whose the
%           value should be prescribed - related to Lagrange multiplier of
%           type II
