System models (1D)
Vehicles, HVAC plants, batteries as 1D models.

Screenshots and a short video come with the listing (AL.3).
Overview
System models (1D) is planned as the add-on for lumped, one-dimensional models of whole systems such as vehicles, HVAC plants and batteries, in PartCraft and BimCraft. It is listed under row XE.12 of Track XE and is planned, not available. The engine under it, lib/sys, is built and tested in the repository, but no app mounts it yet, so nothing can be added or used today.
Who it’s for
- Engineers who want to check how a system behaves over time before detailed design (planned).
- Teams that already describe components in a Modelica-style text and want to read it (planned).
What you can do
- Nothing yet. This is a plan. The intended steps are: build a system from component models for hydraulic, thermal, electrical and mechanical parts, run it over time and read the results.
Methods and standards
Planned, from the engine's design: component models joined at ports, with the whole system solved as equations, and a reader for a subset of the Modelica language.
Data and sources
No data ships. Component parameters are typed by the person.
Verification
Planned: no test yet at the add-on level. The engine has its own suite, tools/sys-test/test.mjs, which the session log docs/0.8-sessions/xe-network_PART_3.md records as 46 passed, 0 failed.
Limits
Planned, not available. Row XE.12 is marked partial: the engine is built, but no host mounts it. Limits stated for the engine: no state events or hybrid switching, no analysis of algebraic loops, no AC small-signal analysis; the Modelica reader handles a flat subset only and does not map the mechanical standard library classes.
Files and formats
Planned: reads a flat subset of Modelica text. Output formats are not yet decided.
Get started
- This add-on is planned and cannot be added yet.
- Follow row XE.12 on the roadmap to see when it moves to the lab.
Languages
No languages are listed for this add-on yet. Its maker may add some.
