Calculation method

Calculation method

Selected course count

First integer courses 1..1000 for which target/courses−unit height is within joint range; zero if none.

Adjusted bed joint (mm)

Target/courses − unit height; zero when no valid course count.

All feasible [courses,joint mm]

Enumerated supported course/joint solutions.

Symbols and units
a
Target finished height including top bed joint (mm)
b
Supplied minimum bed joint (mm)
c
Supplied maximum bed joint (mm)
d
Unit height (mm)

Use the units shown. A list keeps the order in which you enter its values. The symbol ^ means “raised to the power of”.

Assumptions & limits

Assumptions & limits

  • Exactly one bed joint per course including top bed joint. This convention must match measured target; no structural joint approval. Supported limits: Positive target/unit and 0≤minimum≤maximum. Up to 1000 courses.
