SimuPipe CalcumberSimuPipe's answer
SimuPipe brings desktop-grade pipe flow simulation โ liquid and compressible gas, with Crane TP-410, IEC 60534 and ISO 5167 standards built in โ to the browser as a visual drag-and-drop editor, at a fraction of the cost of legacy tools.
Calcumber's answer:
SimuPipe's answer
SimuPipe gives you desktop-grade pipe flow simulation โ liquid and compressible gas, with Crane TP-410, IEC 60534 and ISO 5167 standards built in โ right in your browser, with nothing to install. Legacy tools like AFT Arrow and FluidFlow cost thousands and tie you to a Windows desktop; SimuPipe has a genuinely usable free tier and Pro at โฌ39/mo. Same engineering rigor, visual drag-and-drop workflow, a fraction of the cost.
Calcumber's answer:
SimuPipe's answer
Primary audience: Mechanical, process, and piping engineers โ plus consultants and students โ who need to size and analyze pipe networks for liquids and compressible gases, but don't want the cost or desktop lock-in of legacy tools like AFT Arrow or FluidFlow.

SimuPipe's answer
As a newly launched product, SimuPipe is building its user base among independent mechanical, process, and piping engineers, consultants, and students worldwide.
Calcumber's answer:
SimuPipe's answer
SimuPipe was built to bring desktop-grade pipe-flow simulation proper compressible-flow solvers with Crane / IEC / ISO standards โ to a fast, affordable web app, without the cost or Windows lock-in of legacy desktop tools.
Calcumber's answer:
When starting for a Master of Advances Study in Energy Systems, I was looking for a suitable state-of-the-art calculator. Then I built my own Calculator Calcumber and now the Eastern Switzerland University of Applied Sciences is using Calcumber for teaching students in thermodynamics.
