I have imported structural data with the help of the import functions or direct interfaces. How does the material assignment work, so that materials are also accepted by the design modules?

Answer

In most cases, only the material's name is transferred. If the name differs from the Dlubal Material Database name, neither the base parameters (modulus of elasticity, shear modulus, etc.) nor the additional properties (yield strengths, tensile strengths, limit strains, etc.) are defined. In such cases, it is not even possible to determine the internal forces of the structure.


Some interfaces (Revit, for example) are able to transfer the basic properties. However, the design modules present problems because they require additional material properties. These are only available as information in the databases specific to Dlubal.

We can resolve this topic by linking the name of the imported material with the unique name of the Dlubal material library. This linking can be done in the conversion tables. To open the tables, click "File" - "Import" in the "Details" tab. The handling is relatively simple. On the left, enter the material name from the export file or the CAD application. On the right, the name according to the Dlubal Material Database. It can also be opened directly.

If you have several entries with a similar notation, you can use so-called "Regular Expressions". Further help can be found in the conversion file itself. The path is shown in the detail settings.

The user is requested to create own tables. Dlubal can not provide any tables due to the multitude of programs and notations.
