Answer:
If you want to consider the load cases again, please perform a new RWIND Simulation calculation. If you want to perform the calculation of the existing combinations, please remove the RWIND Simulation load cases from the Wind action before deleting the FE mesh; then the combinations are created again and it is possible to perform the calculation.
Question
My RFEM file includes some RWIND Simulation load cases. After deleting the FE mesh, these load cases are no longer available. However, these load cases are still available in the automatically generated combinations and I get an error message when starting the calculation. What can I do?

Structures are naturally three-dimensional. However, because it was impossible to perform calculations on three-dimensional models easily in the past, the structures were simplified and broken down into planar subsystems. With the increasing performance of computers and related software, it is often possible to do without these simplifications. Digital trends such as Building Information Modeling (BIM) and new options for creating realistic visualized models reinforce this trend. But do 3D models really offer an advantage, or are we just following a trend? The following text presents some arguments for working in 3D models.
In this article, you will learn how to model and design cable structures in RFEM 6 or RSTAB 9.
This article describes and explains the influence of bending stiffness of cables on their internal forces. Furthermore, the text provides information on how this influence can be reduced.
The ASCE 7-22 Standard [1], Sect. 12.9.1.6 specifies when P-delta effects should be considered when running a modal response spectrum analysis for seismic design. In the NBC 2020 [2], Sent. 4.1.8.3.8.c gives only a short requirement that sway effects due to the interaction of gravity loads with the deformed structure should be considered. Therefore, there may be situations where second-order effects, also known as P-delta, must be considered when carrying out a seismic analysis.
Use the "Independent mesh preferred" option in the FE mesh settings to create an independent FE mesh for the integrated objects. This allows you to generate a significantly more detailed and precise FE mesh for individual objects that are integrated into one another.
In the "Edit Section" dialog box, you can display the buckling shapes of the Finite Strip Method (FSM) as a 3D graphic.
In RFEM 6 and RSTAB 9, you have the option to enter "Visual Objects" as guide objects. You can import the file formats 3ds, stl, and obj.
These objects allow you to create a better reference to the dimensions.
Do you have individual column sections and angled wall geometries, and need punching shear design for them?
No problem. In RFEM 6, you can perform punching shear design not only for rectangular and circular sections, but for any cross-section shape.
Why is the surface pressure distribution in RFEM different from the corresponding surface pressure distribution in RWIND Simulation?
My RFEM file includes some RWIND Simulation load cases. After deleting the FE mesh, these load cases are no longer available. However, these load cases are still available in the automatically generated combinations and I get an error message when starting the calculation. What can I do?
Are there any facade surfaces in RFEM to transmit wind loads to the main structure?
Does the software RWIND Simulation account for the internal pressure coefficient (GCpi) from the ASCE 7‑16?
Is the Gust-effect (G or Gf) from the ASCE 7‑16 Sect. 26.11 considered in RWIND Simulation?
Does the software RWIND Simulation consider the wind directionality factor (Kd) from the ASCE 7‑16?
