Storage declaration

Declares local typed storage with an initial snapshot and sample period.

2026-10-27

Behavior

Each model instance owns independent storage. Readers see the old snapshot during a sample; an enabled writer prepares the next one.

Interface

Storage declaration interfaceInputs or arguments on the left, observed outputs on the right. Conserving terminals appear below the component. The tables give units and behavior.Storage declarationStudio block
Original Lemonergy interface view. Lines identify ports; they are not a completed simulation circuit.

This reference describes a studio block; its configuration fields are listed below. It has no connected Studio ports.

Parameters

Defaults are initial model values. Select values for your own model and operating conditions.

Equations and rules

  • snapshot[0] = initial
  • snapshot[k+1] = write[k] if enabled; snapshot[k] otherwise

Connected concepts

Limits and interpretation

  • Exactly one local declaration and at most one writer per storage name. No global cross-model storage or same-sample write visibility.

Reference basis

This software operation is defined by its public contract and worked example; no external research result is claimed.
