Energy models, daylight, airflow, and room acoustics are the simulations published here. The list is short. Windows is on about half of these cards. The browser covers the cloud studies. No card names a phone.
DesignBuilder and IES Virtual Environment are paid trials on Windows, aimed at whole-building energy plus HVAC and daylight. OpenStudio is the open source energy modeling listing on Windows, macOS, and Linux, and the tasks include EnergyPlus and ASHRAE 90.1 Appendix G. SimScale is freemium in the browser for CFD, FEA, and thermal studies. Treble Web Application is a paid trial in the browser for acoustic simulation and speech intelligibility.
About half of these simulation listings include a free way in. The others are paid or paid trial. Compare the physical question each card names, then the pricing type.

OpenStudio is open source on Windows, macOS, and Linux. SimScale is the freemium browser option for CFD, FEA, and thermal work. Spacio is freemium in the browser for early massing, daylight, and compliance review. DesignBuilder, IES Virtual Environment, and Treble Web Application are paid trials.
Both are paid trials on Windows. DesignBuilder's tasks include energy simulation, HVAC modeling, daylight, and CFD comfort studies. IES Virtual Environment's tasks include building energy modeling, thermal comfort, daylight simulation, HVAC sizing, and regulatory compliance checks.
Treble Web Application is the acoustic listing. It is a paid trial, browser only, and the uses include room acoustic prediction, speech intelligibility, and concert hall tuning. The energy and CFD cards in this hub do not list acoustic simulation.
NVIDIA Omniverse is the paid listing for USD scene assembly, live sync between apps, physically based rendering, and simulation orchestration. Platforms are Windows and Linux. OpenStudio is the other listing here that names Linux. Omniverse does not include a free tier.
Desktop studies here usually name Windows. The browser covers SimScale, Treble Web Application, and Spacio. OpenStudio is the listing that names macOS, and it also lists Windows and Linux. iOS and Android are not listed on this page.
