Study dashboards and simulation plots, Maccor recorded procedures, MF4 export, and a faster protocol simulator

​
Simulation plots and study dashboards

Project dashboards can now hold simulation plots as well as measurement plots. Pick runs by filtering the simulations table (including on inputs and metrics), either as a fixed set or as a saved filter rule that picks up new completed runs when refreshed, then preview them in a compact plot drawer and save the plot. Metric plots are scatter plots with hover detail, and time-series legend fields are configurable.A study can now have its own dashboard, kept with the study rather than in the project’s dashboard list. A study’s creator controls its dashboard and which simulations it contains; anyone else can view and preview results, or Copy study to get their own editable copy with its dashboard and plots. The study list shows each study’s creator, with an All / Mine toggle.

​
See the procedure a Maccor run recorded

Maccor raw (binary) data files, which were previously marked unsupported, are now read for the test procedure the cycler recorded in them. A complete recording is added to the protocol library (or matched to a protocol already there) and linked to the run’s measurement automatically. Raw files uploaded before this change have been re-read.On a measurement page, the protocol now has its own Protocol card: change, link or unlink the protocol, see whether it matches what the cycler recorded, and Replace with what the cycler recorded when it differs. The raw file’s page shows the recorded procedure too.

​
Export measurements as MF4

The measurement page’s Download data menu now offers MF4 (ASAM MDF4) alongside Parquet and CSV, for use in CANape, asammdf and other MDF tools. Channels carry their units (e.g. Voltage in V), and the download includes a README showing how to read the files with asammdf.

​
Faster protocol simulations

Long protocol simulations spend much less time outside the solver: a 1,000-cycle ageing protocol runs about 3× faster, with identical results.
Improvements
  • Cycle-level capacity and energy. Measurements and simulations now include Cycle discharge capacity [A.h], Cycle charge capacity [A.h], Cycle discharge energy [W.h] and Cycle charge energy [W.h], which accumulate across every step of a cycle and reset at the next. Existing measurements have been updated, and the columns are included in data downloads.
  • Raw files on the measurement page. A Raw files card lists the files a measurement was built from, what each did (created, replaced or extended it) and links to each file’s page. The Details, Analyses and Raw files panels can now be collapsed.
  • Project Contributors can delete the project content they can create and edit. Deleting the project itself, its members and roles, live-sync sources and raw-data issues stays with Project Admins.
  • Every protocol needs a name. The simulation builder always asks for one, prefilled from an uploaded file or a generated protocol, and won’t run with a name another protocol already uses.
  • Protocol names link to the protocol on the simulation page, in measurement tables and on the lab channel schedule. The simulations table groups its Columns panel and links its Protocol column.
  • Column widths are remembered. A column you resize keeps its width through search and page reloads, on every table.
  • Failed measurements show a red alert icon beside their name instead of a separate column.
  • Live sync sources that are still being set up show amber on the Live sync page, in the top bar and on project Home, instead of looking healthy.
  • Dashboards load faster, fetching all their plots in one request.
  • Parameter metrics. Metric suites can define metrics such as stack thickness or areal capacity, computed directly from a parameterized model’s parameters.
Fixes
  • Simulating a saved protocol fills in every input it references, including inputs used only in its global settings, from the protocol page, a study and the full setup page.
  • Table rows can’t lose their controls. The selection checkbox, View button and row menu can no longer be hidden from the Columns panel.
  • The last row of a table is no longer partly covered by the scrollbar strip on macOS, and single-page tables no longer show a pagination footer.
  • The Voltage components section is only offered for models that have a voltage breakdown.
  • Opening a raw file’s plot no longer fails intermittently right after the file was updated.
Improvements
  • ElectrodeBalanceFromFirstCycleEfficiency supports composite electrodes (e.g. graphite/SiOx) through options, and now computes the formation loss against the positive electrode’s capacity, so it follows design changes to loading. "Nominal cell capacity [A.h]" is no longer an input, and results change for existing configs.
Fixes
  • Data fits and validations now use the model’s saved simulation settings (mesh and solver) instead of the defaults.
  • CycleAgeing warns with the cause whenever a metric is scored as a failed evaluation, and a fit where every evaluation fails raises an error instead of returning the initial guess.
Improvements
  • Every record links to the web app. Detail get calls return url (the record’s page in the app) and api_url (its canonical endpoint).
  • Per-run simulation settings. Simulation batches take simulation_settings (solver, var_pts, submesh_types, spatial_methods, discretisation_kwargs), overriding the model’s and parameterized model’s settings for that run. discretisation_kwargs can also be saved on models and parameterized models.
  • Repeat inline simulations reuse stored results. Submitting the same inline parameterized model again reuses the existing one instead of creating a new copy or failing on its name.
  • Protocol groups. client.protocol_group creates, lists, updates and deletes groups, and protocols take protocol_group_id.
  • Projects carry your own access. Project records include my_role and my_permissions for the caller, and no longer embed every member’s role, so project lists are much smaller.
  • Metric suite surrogates. client.metric_suite.create_surrogate(...) trains a model that predicts a suite’s KPIs anywhere in a range of design variables without simulating.
  • Sites have a timezone (Site.timezone, an IANA name defaulting to America/New_York).
Fixes
  • Under termination="events", a constant-current or constant-power step whose last logged sample belongs to the next step now takes its end value and setpoint from its own samples, so simulated steps no longer stop early.
Fixes
  • Voltage sweeps (e.g. slow cyclic voltammetry) with no explicit duration run until their setpoint reaches an end condition, instead of stopping at 24 hours.
  • Sub-procedure jumps in protocols imported from Maccor, Arbin or UCP files resolve correctly, and an unresolved block-level goto is reported when the protocol is saved.
Improvements
  • run-simulations covers per-run simulation settings, metric suite surrogates and protocol groups.
  • manage-protocols and discover-api document protocol groups.
  • manage-projects, manage-cells, run-pipelines and discover-api link to records through their url.
  • manage-equipment documents site timezones.
