The Material Coefficient values provide numbers that reflect the material property and are the fractional change in length per unit change in temperature.
A scale with a coefficient of 11.5 microns/meter/degree C becomes 0.0000115 meters/meter/degree C or just 0.0000115/degree C.
This can be thought of as meters/meter/degree C or inches/inch/degree F but since the length in both the numerator and denominator are in the same units they divide out.
Entry Name: QualToolMaterialCoeffient
Entry Type: Character string used to specify a default coefficient for qual tools. The default value is NONE(). If a value is provided, it is used for qual tools that have not selected a coefficient as part of the definition of the qual tool. The value should be the fractional change / degree C.
