armi.matProps.interpolationFunctions module

Some basic interpolation routines.

armi.matProps.interpolationFunctions.findIndex(val: float, x: list) → int[source]

Find the location of the provided value in the provided collection.

Parameters:

  • val (float) – Value whose index is needed in x

  • x (list) – List of numbers

Returns:

Integer containing index wherein x[i] <= Tc <= x[i+1]

Return type:

int

armi.matProps.interpolationFunctions.linearLinear(Tc: float, x: list, y: list) → float[source]

Find the approximate value on a XY table assuming a linear-linear curve.

Parameters:

  • Tc (float) – Independent variable at which an interpolation value is desired.

  • x (list) – List of independent variable values

  • y (list) – List of dependent variable values

Returns:

Float containing final interpolation value based on a linear-linear interpolation.

Return type:

float

armi.matProps.interpolationFunctions.logLinear(Tc: float, x: list, y: list) → float[source]

Find the approximate value on a XY table assuming a log-linear curve.

Parameters:

  • Tc (float) – Independent variable at which an interpolation value is desired.

  • x (list) – List of independent variable values

  • y (list) – List of dependent variable values

Returns:

Float containing final interpolation value based on a log-linear interpolation.

Return type:

float
