CDB Reader

Methods for loading and accessing data from a CDB file are provided by the SOFiSTiKCDBReader class.

The following minimal example shows how to create a reader instance and use it to load and access truss data.

from py_sofistik_utils import SOFiSTiKCDBReader


if __name__ == "__main__":

    reader = SOFiSTiKCDBReader(
        ".../path/to/cdb/file/",
        "cdb-file-name",
        ".../path/to/dlls/",
        2025
    )

    reader.open()
    reader.truss_data.load()
    reader.close()

    # some post-processing
    initial_length = reader.truss_data.get(100, "L0")
    # ...

Units of Measurement

All quantities retrieved from a SOFiSTiK CDB file are stored without conversion. Therefore, they should be interpreted in their native units, summarized below for convenience:

• Forces (internal forces, reactions, loads, etc.) are expressed in kN

• Moments (internal moments, reactions, loads, etc.) are expressed in kNm

• Displacements (nodal displacements, imposed loads, etc.) are expressed in m

• Rotations (nodal rotations, etc.) are expressed in radians

For additional details, refer to the SOFiSTiK documentation.

Notes

Each instance can manage one single CDB file.
