Frequently Asked Questions (FAQ)

AnswerIn RFEM, the easiest way is to use the "Plane Surfaces" → "Annulus" feature. This allows you to model the reinforcement rings very quickly and easily. Then you can extrude the inner line into a surface, the chimney is already generated. Now, the existing annular surface is copied upwards and the corresponding stiffeners are modeled. You can use the "Rotate" command to distribute the stiffeners over the chimney perimeter.
AnswerIn the RWIND Simulation program, a stationary flow analysis of incompressible gases is implemented. The principles and formulations used for this do not change over time. Thus, the calculation gives a result set without temporal variation. The effect of a "Kármán vortex street," in which counter-rotating vortices develop behind a body around which flows, results in a temporal change of the flow effect. Therefore, this fluid-mechanical effect cannot be simulated in RWIND Simulation.

Wind Simulation & Wind Load Generation
With the stand-alone program RWIND Simulation, wind flows around simple or complex structures can be simulated by means of a digital wind tunnel.
The generated wind loads acting on these objects can be imported to RFEM or RSTAB.
“Thank you for the valuable information.
I would like to pay a compliment to your support team. I am always impressed how quickly and professionally the questions are answered. I have used a lot of software with a support contract in the field of structural analysis, but your support is by far the best. ”
