Simulation panels
Experiment creation, experiment results, and scenario creation and editing open in a panel beside the main view. The list or canvas stays visible and usable alongside it.
Select and resizeCopy link to this section
Click an experiment or scenario once to open its panel. The selected row has a shaded background and a dark left edge. With focus in the list, press Up or Down to select and open the previous or next row. Focus stays in the list so you can keep browsing with the keyboard.
Drag the divider between the list and the panel to adjust their widths. The panel keeps your chosen width when you return from fullscreen. If the window or docked assistant leaves less room, the panel fits the available space while keeping part of the list visible.
Expand and returnCopy link to this section
Click Expand to fullscreen in the panel header to cover the list while keeping the vertical tabs visible. The header shows the tab and resource names, such as Scenarios › Mars Orbit. Click Scenarios or Experiments in the breadcrumb, or Show as panel, to return to the list beside the panel. The same form or results stay open: unsaved edits, expanded charts, and scroll position carry across the resize.
Each tab remembers its selected resource and panel or fullscreen presentation while the current model is open. Opening another model clears these remembered selections. Returning to a fullscreen resource shows it at full size immediately. Save scenario edits before switching tabs; unsaved form edits are not retained across tab changes.
Fullscreen belongs to Simulate. Expanding a creation form from Edit opens its Simulate tab. Switching to Edit or Actual leaves the creation form in a side panel so the main view remains usable and your draft stays open.
Panels open and close with a short slide and fade, while the main view adjusts alongside them. Selecting another scenario updates the form in place without replaying the panel animation. Expanding and collapsing animate the panel width and the tab name in the header. These transitions follow Animations in Settings and your system's reduced-motion preference; manual resizing stays immediate. Forms use a consistent, compact gap below the header before the first field or section title.
Both size controls and Close panel sit together on the header's right edge. Headers without a subtitle match the list header's height. Escape closes the panel while focus is inside it, unless an editor or menu handles Escape first. Closing an experiment's results leaves the experiment running. Save a scenario's edits before closing it or selecting another scenario to keep them.
When scrolling a scenario form, section headers pin directly below the panel header. The initial spacing above the form scrolls away with its content.
Alongside the AI assistantCopy link to this section
A docked AI assistant takes space beside the main view and the simulation panel. Opening, closing, or resizing the assistant adjusts the space available to both. Fullscreen fills the main view beside the assistant. A floating assistant sits above the workspace.
Links and browser historyCopy link to this section
On the Petrinaut website, the address includes the open experiment or scenario and whether it is fullscreen. Browser Back and Forward restore that view and its size.
Switching to Edit or Actual keeps that mode on refresh or when sharing the link. The remembered resource and its size remain available when you return to Simulate.
A scenario link requires the same model with that scenario saved. A link to a creation panel opens an empty form. Experiments belong to the current session; opening an experiment link after that session has ended shows an unavailable message and does not rerun it.
