No-code parameter studies for simulation engineers

An engineer running design exploration in Altair Inspire or Ansys Mechanical wants to sweep through ten combinations of load magnitude, material stiffness, and geometry thickness to find the best performing variant. Doing this manually means running ten simulations by hand, changing inputs one at a time, and tracking results in a spreadsheet. Doing it automatically means writing a script — and the complaints about 'requires coding to use', 'interpolation functions are not so easy', and 'little automations needed' all point to the same ceiling: users who understand the physics can't execute the automation without a separate skill set.

This gap exists because CAE vendors treat scripting as a power-user feature and package design exploration as a premium add-on module — often sold separately at significant cost on top of the base license. So the engineer who just needs to run a simple parameter sweep either pays for an enterprise optimization module they'll use for one feature, or they hand-script something brittle. Neither option is proportionate to the task.

What's missing is the ability to define a parameter study the same way you'd fill out a table: here are my variables, here are the ranges, run all combinations and show me a ranked output. No code. No separate module license. The interpolation complaint is telling — users want to define relationships between variables (if thickness goes up, reduce mesh density here) and they have no way to express that without code.

This is a business because every product development team running simulation does parameter studies, and doing them manually is provably slower and error-prone. A team running two hours of manual bookkeeping per study, across ten studies a month, is spending real engineering hours on data entry. The need doesn't go away — it recurs with every new design iteration cycle.

What to build

Build a standalone desktop app that connects to Ansys Mechanical and Altair Inspire via their existing scripting APIs, reads a user-defined parameter table (variable names, ranges, step sizes, conditional rules), orchestrates the simulation runs without user intervention, and outputs a ranked results table with side-by-side comparison of key metrics — no coding required from the engineer.

Where to start

Target Ansys Mechanical users first, specifically at small-to-mid engineering consultancies that can't justify the cost of Ansys optiSLang or similar optimization add-ons — the pricing gap between 'nothing' and 'enterprise optimization module' is wide enough that even a modest tool at $150/month wins on ROI.

The hard part

Connecting to multiple CAE solvers reliably requires maintaining integrations against each vendor's API, which changes with software versions — supporting Ansys and Altair simultaneously from day one may force trade-offs that make the first version feel too narrow to sell broadly.

How it makes money

Monthly per-seat subscription (~$120–180/month) with a free tier capped at three active parameter studies, expanding to unlimited studies and multi-solver support on paid plans.
