SolverSection
File Object Type 
You can refer to this file object type in any formula, macro, module, or other script in Blockpad. You can use either its name or its full path:

To refer to it by name, use
SolverSection
(make sure the library Library.Docs.Objects is included with Include Libaries)  To refer to it by its full path, use
Library.Docs.Objects.SolverSection

A Solver Section is used to solve systems of equations.
To use a solver section, type in equations with the variable names you wish to solve for. These must be unused as value names in the frame. When there is enough information to solve the system of equations, the results will appear at the bottom of the section.
Insert a solver section:
 While inside a report or multiline cell, select the insert tool.
 Select Solver Section.
 Click OK.
Methodology
For a linear system of equations, solver sections solve the system directly with matrix operations. Units are determined directly based on the equations.
For a nonlinear system, Blockpad attempts to solve the system through multivariable NewtonRaphson iteration. By default, the initial guess for each variable is 0. Alternative initial guesses may be set through the Initial Guess Property. To control result units for a nonlinear system, set the the initial guess to a number with the desired unit.
If the solver is unable to converge on a solution, each variable is set to an error state. You can view the iteration log of a solver section in the formula browser using the show in formula browser tool.
Examples
Here a free body diagram is solved with the solver section and depicted using the Blockpad drawing tool.
This example uses a solver section to find the friction factor for a head loss calculation. The initial guess for f is set to 0.01.
Here the solver section is used to find the length in a buckling equation.
Notes:
 Because capture variables is set to no by default for solver sections, you can reference the results in formulas using only the variable names.
 You can conditionally hide a section using the hide property.
