Run rigorous process simulations in your browser — no Aspen seat required
Laminar is a browser-based process simulation workspace for engineers, researchers, and universities that need Aspen-class workflows without starting at Aspen-class pricing. Start by understanding the product, trying a public demo, and browsing example flowsheets. Create an account when you are ready to run and save real work.
Evaluation Flow
From curiosity to workspace
Step 1
Understand the product
Validation
Compare against benchmark results
Economics
See sizing and TEA are built in
Collaboration
Share workspaces after signup
Step 2
Touch the product without signup
AI flowsheet generation demo
Prompt a process idea and inspect the generated unit operations and stream topology.
Template gallery
Browse sample processes by separation, reaction, gas treatment, power, and heat integration.
Step 3
Create an account when you need a real workspace
With account
Save projects, run full simulations, import process files, collaborate, and export work.
Without account
Stay in evaluation mode with public demo surfaces and product documentation.
Switching simulators?
Import your existing flowsheets and pick up where you left off
Upload your simulation backup files (.bkp format) and Laminar converts them to editable flowsheets automatically — streams, unit operations, and thermodynamics included. In your browser, in under 5 minutes.
What Laminar is
A product landing page should explain the product before it asks for a login.
This is the public front door. It is meant to help someone decide whether Laminar is relevant before they jump into authentication or a blank workspace.
Build and simulate real flowsheets
Create process diagrams in the browser, define thermodynamics, run recycle convergence, and inspect stream results without installing desktop software.
Migrate from legacy simulators
Import legacy simulation files, review validation results, and confirm Laminar matches your production workflows before you commit.
Move from simulation to decisions
Go beyond steady-state calculation with equipment sizing, economics, analysis panels, collaboration, and AI-assisted flowsheet generation.

Three public paths before anyone commits to the app
Someone new to Laminar should be able to understand what it is, inspect examples, and touch a lightweight demo before deciding to sign up.
Try the public demo
Describe a process in plain English and see Laminar generate a flowsheet structure without creating an account.
Open demoBrowse example flowsheets
Explore representative templates by process type, industry, and difficulty before you commit to a workspace.
Browse examplesReview validation and pricing
Read migration-oriented material first if you are comparing Laminar against Aspen, HYSYS, or campus-license alternatives.

What becomes available after signup
Public preview scope
What the unsigned experience is and is not
That separation is intentional: the public side explains and demonstrates the product, while authenticated workspaces handle saved simulations, solver runs, and private process data.
Who it is for
The audience is broader than people already prepared to log in
SME engineering firms
Get browser-based process simulation without the seat pricing and IT overhead that usually block small teams.
Universities and classrooms
Give students a no-install environment for assignments, validation exercises, and shared examples.
Researchers and process developers
Work with native thermodynamics, compound tools, and sensitivity studies in a stack that is easier to inspect and extend.
Next step
Understand the product, try the public surfaces, then open the app.
That is a healthier funnel than dropping every visitor straight into a tool-shaped entry point.
