DPF Core FieldsContainer time-step pagination with result scoping
Goal: confirm whether Ansys DPF Core paginates time-step or frequency-set results when a Scoping bounds a query over a large simulation dataset, or whether the operator fully materializes a FieldsContainer. DPF operators accept a Scoping object to limit node or element IDs and selected time or frequency set indices. A FieldsContainer groups result fields by time and set and is normally accessed by index or iteration. No standard page-size, offset, or cursor parameter is documented for stepping through a FieldsContainer.
Behavior may differ across releases such as 2023R1, 2024R2, and 2025R1. Scoping limits entities but does not by itself cap memory if the selected subset is large, and memory depends on whether results compute in place or stream.
Questions:
- Does DPF Core expose a page-size, offset, or cursor mechanism to retrieve a bounded range of time steps without loading the full FieldsContainer?
- If pagination is unavailable, what is the recommended release-specific pattern for processing large time-history results in bounded chunks while controlling memory?
- How does upstream scoping interact with lazy evaluation when the selected entity subset remains large across many time steps?
