Open a MIKE+ .sqlite model and report the active simulation/scenario/model, unit system, the list of simulation setups (msm_Project), scenarios, and element counts (nodes/links/catchments). Read-only. Needs MIKE+ + license.

Read parameter values from a MIKE+ table (e.g. msm_Link, msm_Node, msm_Catchment) for the given columns and optional element MUIDs. Read-only. Needs MIKE+ + license. Use this to identify current parameter values.

Set parameter values in a MIKE+ table for specific element MUIDs (e.g. change a pipe Diameter or Manning roughness). Returns before/after for the affected rows. MUTATES the database — ALWAYS use a copy. Needs MIKE+ + license. Pass 'muids' to scope the change; set all=true only when you intend to change every row.

Render a stacked two-panel rainfall-runoff figure (rain inverted on top, flow on bottom) in the house style. Flow comes from a .res1d element; rainfall optional from a .dfs0. No license needed.

Render a single-panel time-series plot (a quantity at an element) in the house style. No license needed.

Render a network layout map of a MIKE+ model from a .res1d — reaches/pipes as lines, nodes as points, equal-aspect, house style. Good for an overview figure. No license needed.

List what is inside a MIKE+ .res1d: quantities (WaterLevel/Discharge/...), element counts (nodes/reaches/structures/catchments) with sample ids, and the time range. No license needed.

Per-quantity peak summary (peak value, element, chainage, time) from a MIKE+ .res1d. No license needed. NOTE: this is the GLOBAL max over the whole run, which can fall in the warm-up/initial-condition period (a base-flow value near t=0) rather than the storm peak — pass skip_hours to exclude an initial window and always check peak_time.

Extract one time series (a quantity at an element) from a MIKE+ .res1d as times+values (downsampled to max_points). No license needed.

Run a MIKE+ simulation headless via the MIKE 1D engine. Runs the model's active simulation unless 'simulation' is given. Returns the result file paths plus the engine log tail. Needs MIKE+ installed + a valid license. ALWAYS run on a COPY of the model (mikeplus has no undo).
