I have tried RFEM. It's easy to get started with this program. The support team is very accessible and works efficiently.
I don't regret my choice at all; far from it, I recommend it.
In RFEM, oriented strand board (OSB) material is available for the USA and Canada. The material parameters are taken from the "Panel Design Specification manual".
The "Bracing in Cells" function allows you to generate diagonal bracing with just a few clicks. You can find this feature under Tools → Generate Model – Members → Bracing in Cells.
In RFEM and RSTAB, you can visualize the flow field quantities of pressure, velocity, turbulence kinetic energy, and turbulence dissipation rate for the wind simulation.
The clipping planes are aligned with the respective wind direction.
In RFEM, you can generate surfaces from members with the library cross-sections as well as from the members with the RSECTION cross-section.
