A change log of the ifc2ca files

01/03/21

• Add salome and code_aster script files for a "bonded" case, meaning all connections between elements are considered fixed. This allows to consider exported ifc files from commercial software that do not include connections between surface elements (see building_02 example)

14/10/20

• Add curve connections between elements and as supports according to the defined orientation - stiffness is not yet considered

17/08/20

• Add rigid links for point connection to elements

14/07/20

• Add internal springs for point connection to elements according to the defined orientation
• Add external springs for point connections according to the defined orientation

27/05/20

• Add orientation for point, curve and surface geometries
• Calculate final geometry and orientation based on object placement transformation
• Add warnings in the json file to show any corrections considered while parsing the ifc file from ETABS with a model with rigid links
• Reduce file size by adding material and profile db in the json file and referencing them in the element objects
• Implement internal releases for curve-to-point connections with any arbitrary orientation

22/03/20

• Calculation of section properties for I symmetric profile if not provided (assuming fillet radius is zero)
• Added geometry of planar structural surface members
• Refactored the ifc2ca.py script
• Added support for rigid links
• Added advanced meshing script to correctly simulate connections and independent meshing of structural elements (no common nodes)

26/02/20

• Changed section to profile and added I profile
• Modified material and profile schema with mechanical and common properties
• Added geometry identification for point connection from representation
• Added connections along with supports based on the number of elements a connection is applied to

09/02/20

• First implementation for straight structural curve elements and point connections
