Answer:
The asynchronous calculation is used when a self-created program should only access RFEM or RSTAB and continue working in parallel. When the calculation is complete, the event is transferred via a delegate. You can find a C# example in a Visual Studio project under Downloads below.
Question
How does the asynchronous calculation via the COM interface work?
Do you have any questions?
If you read out the results of a surface by means of the COM interface, you get a one-dimensional field with all results at the FE nodes or grid points. To get the results on the edge of a surface or along a line within the surfaces, you have to filter out the results in the area of the line. The following article describes a function for this step.
When editing elements via the COM interface, selecting elements is often a problem because it cannot be carried out visually via the work window. The selection can be particularly difficult for models that have been created via the program interface and are then to be modified using a separate program. Apart from the exception, when the selection was made previously via RFEM, there are several alternatives for programming.
RFEM and RSTAB are able to cover a large number of branches in the building and construction industry with their generally usable structural frame analysis and FEM programs. Designing cable structures is thus also possible in both software solutions. Some assistance tools for modeling and design will be presented in the following text.
RF-COM/RS-COM is a programmable interface that allows the user to expand the main programs RFEM and RSTAB with customized input macros or post‑processing programs. A tool to copy and move selected guidelines in RFEM will be developed in this article. It is also possible to copy or move the guidelines to another work plane. VBA in Excel will be used as the programming environment.
In RFEM, the 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 the ultimate configuration of the steel joint design, you have the option to modify the limit plastic strain for welds.
