GeoDict Copilot
GeoDict experts get more done, and more people in R&D can use GeoDict.
The Copilot is an AI-assisted desktop application for GeoDict that helps R&D teams set up, run and analyse simulation workflows without having to handle every technical detail manually.
We are opening the Copilot to two or three R&D teams to apply it to real materials and simulation workflows.
Operating GeoDict
GeoDict is powerful. Using it efficiently takes time.
Setting up simulations, choosing the right modules and parameters, running studies, processing results and turning workflows into something colleagues can reuse requires substantial experience.
The Copilot takes care of much of this operational work, so your team can focus on the material, the simulation question and the engineering decisions.
GeoDict experts
Let the Copilot handle repetitive tasks such as:
- selecting modules and parameters
- setting up and running simulations and parameter studies
- reading and organising results
- building reusable workflows, GeoApps and Python postprocessing
More people in R&D
Make simulation accessible to more of your R&D team through:
- a natural-language interface to established simulation workflows
- reports that export to PDF, PowerPoint or Word
- values reported with unit and source result file
- macros that stay in the project folder and rerun without the Copilot
Copilot workflow
01 Ask
Describe the material, question or analysis you want to perform.
02 Copilot
The Copilot translates the task into a validated GeoDict workflow.
03 Simulate
GeoDict runs the simulation on your own hardware.
04 Analyse
Results are processed, documented and connected to your existing R&D workflows.
Demo: FFP2 filter study
Four recordings from one session in the real application. An engineer asks whether finer fibres would filter better in an FFP2 meltblown layer, and the Copilot takes the question from study plan to team report.
1 · Study setup (3 min)
The engineer asks whether 6 µm fibres would filter better than 10 µm. The Copilot proposes a study and names its assumptions. After a “go ahead” it builds the macros and starts GeoDict.
2 · Team report (2 min)
“Make a report for tomorrow’s team meeting, with pictures of both webs.” The Copilot builds the report, and it opens by itself.
3 · Third fibre diameter (3 min)
“Add 8 µm and update the report.” GeoDict runs the third variant and the report reloads with three webs. On request, two charts show how fibre diameter changes permeability and efficiency.
4 · Chart change (1 min)
“Replace the pressure drop bar chart with a line plot over fibre diameter.” The chart is swapped and the report reloads in place.
Application features
Reports and parameter studies

Before it builds a report, the Copilot collects the study data into tables. It reports what the runs gave and leaves the interpretation of the results to you.
A report opens as a page in a tab beside the chat. This one comes from a filter study of 18 FilterDict runs: two fiber diameters, three SVP targets and three face velocities. The buttons at the top pick one computed run, and the numbers and charts below follow the pick.
The bar under the page switches the report between four themes, design, print, contrast and cvt, and exports it to PDF, PowerPoint or Word. Charts and tables have a copy button. The Reports tab opens as a gallery of the reports in your project.
Custom geometry
Some structures have no GeoDict command behind them: a rope of twisted filaments, a battery particle of sintered grains. The Copilot builds them through GAD files and voxel manipulation.
Data and models
Nothing has to leave the building. The Copilot is installed on your machine and drives your GeoDict. The AI model is your choice: Claude, any OpenAI-compatible API, a self-hosted model on your own servers.
The Copilot does not change how GeoDict performs the simulation. It uses validated building blocks to assemble and execute workflows.
In my GeoDict project work I run parameter studies, build tailored workflows and do modelling for my clients. For eight years I have been developing my own tools for that. The Copilot builds on them. I use it in my daily work; tasks that took several days are now done in a few hours.

Pilot projects
We are opening the Copilot to two or three R&D teams to apply it to real materials and simulation workflows. Bring a material or a simulation task you already work on, and see what changes when the software takes care of the mechanics.
