Is it possible to export RWIND Simulation results into a GIS software or any other external program?
Answer
RWIND Simulation results are stored as a VTK format (.vtp and .vtu files) located in the working directory of the project.
The files can be opened in ParaView which is an open source software available at https://www.paraview.org. The data can further exported to many other formats. Becuase ParaView is an open source software and allows the use of custom plugins, it is possible to export data to any custom format.
For more information on ParaView, refer to FAQ 4825.

Answer
In order to be able to assign an eccentricity to a member, it is usually necessary to create it before setting the member.
Another approach is shown in the following example. First, the eccentricity is created and then assigned to an existing member via its interface:
'---------------------Sub SetEccentricity()'---------------------Dim model As RFEM5.modelSet model = GetObject(, "RFEM5.Model")model.GetApplication.LockLicenseOn Error GoTo eDim iModData As RFEM5.iModelDataSet iModData = model.GetModelData' create eccentricityDim eccens(0 To 0) As RFEM5.MemberEccentricityeccens(0).No = 1eccens(0).Comment = "test eccentricity"eccens(0).ReferenceSystem = LocalSystemTypeeccens(0).Start.X = 0eccens(0).Start.Y = 0eccens(0).Start.Z = 0eccens(0).End.X = 0eccens(0).End.Y = 0eccens(0).End.Z = 0eccens(0).HingeAtEndNode = Falseeccens(0).HingeAtStartNode = Falseeccens(0).HorizontalAlignment = Middleeccens(0).VerticalAlignment = Bottomeccens(0).TransverseOffset = Trueeccens(0).ReferenceObjectNo = 2eccens(0).ReferenceObjectType = MemberObjecteccens(0).HorizontalAxisOffset = Middleeccens(0).VerticalAxisOffset = Topeccens(0).StartAdjoiningMembersOffset = Falseeccens(0).EndAdjoiningMembersOffset = FalseiModData.PrepareModificationiModData.SetMemberEccentricities eccensiModData.FinishModification' add eccentricity to memberDim iMem As RFEM5.IMemberSet iMem = iModData.GetMember(1, AtNo)Dim mem As RFEM5.Membermem = iMem.GetDatamem.EccentricityNo = 1iModData.PrepareModificationiMem.SetData memiModData.FinishModificatione: If Err.Number <> 0 Then MsgBox Err.Description, , Err.Sourcemodel.GetApplication.UnlockLicense
End SubMember eccentricities can only be transferred as a field; for this purpose, a field with only one element has been created. In the attached image, the individual elements are itemized with reference to the graphical elements.

In SHAPE-THIN 9, you can model cold-formed sections andeffective cross-sections according to EN 1993‑1‑3 and EN 1993‑1‑5. This is not possible in SHAPE‑THIN 8. -
Answer
Unfortunately, it is not. Dlubal Software requires specialized knowledge in the field of structural analysis; therefore, the student version is only available to students of technical colleges and universities teaching structural analysis, engineering mechanics, and similar subjects.

Answer
The trapezoidal sheet is modeled as an orthotropic surface. In the default setting, the arches of the trapeziodal sheet are in the x directions, which is the same direction of the IPE 120 beams.If you set the orthotropy direction to 90 degrees, that is, perpendicular to the beams, the moments will increase. If the sheet metal arches are perpendicular to the beams, the stiffness in the second direction is very small, so the load is transferred first between the IPE 120 beams.

Answer
The value of the coordinates must lie in the range from -100,000 m to 100,000 m.

Answer
The load cases marked in red, such as LC4 in the image, cannot be designed: Such a load case contains either no loading or imperfections only. When selecting the load case, a corresponding warning appears. -
Answer
Warning 155 appears once the spacing of the stirrup legs of a beam in the transverse direction exceeds the limit value st,max given by the standard (see Eurocode 2, Section 9.2.2 (8)). The problem can be solved by increasing the number of stirrup legs under the settings for the stirrup reinforcement.

Answer
In RFEM and all add-on modules, the units and decimal places are managed in one dialog box.
To adjust this, open Units and Decimal Places under Options.You can modify the settings as you need during the modeling or evaluation. All numerical values are converted or adjusted.

Answer
This setting is used to reduce the effective concrete tensile strength fct,eff. If you expect the crack formation in the first 28 days, you should reduce the effective tensile strength of concrete fct,eff according to EN 1992‑1‑1, 7.3.2 (2). You can enter the corresponding reduction factor. The German National Annex recommends to use fct,eff = 0.50 ⋅ fctm (28d). If you cannot determine a definite point of time for crack formation within the first 28 days, a tensile strength of at least 3 N/mm² for normal concrete should be assumed in accordance with the German National Annex.

First steps
We provide information and tips to help you get started with the basic program RFEM and RSTAB.
Wind Simulation & Wind Load Generation
With the stand -alone program RWIND Simulation, you can simulate wind flows around simple or complex structures by means of a digital wind tunnel.
The generated wind loads acting on these objects can be imported to RFEM or RSTAB.
