Initial Guess

Tool

Built-in

The Initial Guess property controls the first guess that a solver section makes for a solver variable.

Solver sections solve linear systems of equations using matrix calculations, but non-linear sections are solved using iterative methods. For these iterative methods, Blockpad uses a default first guess, which is typically sufficient. However, sometimes it's necessary to provide a first guess for non-linear systems of equations, especially if there are units involved.

Set an initial guess:
  1. In a solver section, select the solver variable you wish to set the guess for.
    • The solver variables are located at the bottom of the solver section, in the shaded area.
  2. Open the properties window.
  3. Under Object, click Initial Guess.
  4. Enter an initial guess.
    • The initial guess box is a formula, so you can enter a number, a value reference, or a calculation.
Notes:
  • It is often necessary to input an initial guess with units for non-linear equations with units.
