Run process simulations from a spreadsheet
The MaximaLabs Excel add-in turns a cell into a process solve. Reference a flowsheet, feed it inputs, and pull stream results back into your worksheet — with formulas that recalculate like any other.
The formulas
Solves the named flowsheet with the input overrides in the given range and returns its status.
Reads a solved stream field — molar flow, temperature, pressure or a component mole fraction — into the cell.
How it works
Four steps from a browser flowsheet to a live spreadsheet model:
- 1
Install the add-in
Add the MaximaLabs helper to Excel (a small xlwings-based workbook add-in).
- 2
Reference a saved flowsheet
Point a cell at a flowsheet you built in the browser with =FLOWSIM.RUN(url, name, inputs).
- 3
Pull results into cells
Read any solved stream value with =FLOWSIM.STREAM(url, id, edge, field) — molar flow, temperature, composition.
- 4
Recalculate
Change an input cell and Excel re-runs the simulation and refreshes the numbers, like any other formula.
