Data lines to define an equation

First line

Number of terms, N, in the equation.

Second line

Node number or node set label, P, of first nodal variable, $u_{i}^{P}$ .
Degree of freedom, i, at above node for variable $u_{i}^{P}$ .
Value of $A_{1}$ .
Node number or node set label, Q, of second nodal variable, $u_{j}^{Q}$ .
Degree of freedom, j, at above node for variable $u_{j}^{Q}$ .
Value of $A_{2}$ .
Etc., up to four terms per line.

Repeat the second data line as often as necessary to define all of the terms of the equation. No more than four terms can be defined on a line. To define another constraint, repeat the entire set of data lines.
