Some variables of the GEMSEO-free version of the beam use case.

class gemseo_umdo.use_cases.beam_model.core.variables.Variable(name, value=None)[source]

Bases: NamedTuple

A variable of the beam use case.

Create new instance of Variable(name, value)

Parameters:

  • name (str) –

  • value (float | None) –

count(value, /)

Return number of occurrences of value.

index(value, start=0, stop=9223372036854775807, /)

Return first index of value.

Raises ValueError if the value is not present.

name: str

The name of the variable.

value: float | None

The default value of the variable.
