- [`scriptSalome.py`](scriptSalome.py): a python script to run in the [`Salome-Meca`](https://www.code-aster.org/spip.php?article303) environment. Creates the geometry and the mesh of the structure
- [`scriptCodeAster.py`](scriptCodeAster.py): a python script to create the input file (`.comm`) for Code_Aster
#### Examples
#### Analysis Models
All examples are contained in a separate repository within the IfcOpenShell organization (Work In Progress).
- `cantilever_01` (model created by Dion Moult)
- `beam_01` (model created by Tandeep Singh)
- `portal_01` (model created by buildingSmart)
- `building-frame_01` (model created by Tandeep Singh)
- `building_01`] (model created by Tandeep Singh)
All example folders contain the following files:
__Input:__
- `{example_name}.ifc`: ifc file of the example
- `{example_name}.json`: json data file of the example
- `bldMesh.med`: mesh file exported from Salome_Meca after executing `scriptSalome`
- `CA_input_00.comm`: command file generated from `scriptCodeAster`
__Output:__
- `result.mess`: message log file of the interpreted commands in Code_Aster
- `result.rmed`: result file on the mesh of the structure to visualize in Salome_Meca
A number of analysis models with all the relative input/output and script files are provided in [this repository](https://github.com/IfcOpenShell/analysis-models) within the IfcOpenShell Organization

### Current Status
_As of 22/03/20:_
- Added beam and building examples
- Added support for I sections and calculation of section properties if not provided (assuming fillet radius is zero)
- Added support for surface members (shells)
- 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)
_As of 26/02/20:_
- Added portal example
- 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
- Applied conditions with elastic stiffness values is still not implemented. Only True/False values are accepted.
_As of 16/01/20:_
- Only line geometries for structural elements and point geometries for supports are considered
- The structure is analysed for gravity loads with a single linear static analysis

## A change log of the ifc2ca files
##### 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
