Creation of the HEX geometry

 

In the present page the edits required in the file Ex_009_abaq.inp are described. The example files are provided in ParaGeo Examples\General Examples\Ex_009\02_Hex_Geometry\Data

1Conversion TYPE is set to "GEOMETRY" in order togenerate the full geometry from the Abaqus mesh (i.e. all lines, surfaces and volumes required to make a mesheable geometry will be generated)

 

2File name is optionally edited (Ex_009_geom in the present case)

 

3The line *CONVERSION OPTIONS, LINE SPLIT=NO is added. This is required for generation of the full geometry from a HEX Abaqus mesh (this prevents generation of multiple individual lines for each HEX element vertex).

 

4At the end of the file the line that reads the spatial grid is deleted (note that reading and element renumbering of the of the spatial grid is only required for HEX models where the spatial grid is defined on an element basis)

 

 

 

Results

 

The results are provided in ParaGeo Examples\General Examples\Ex_009\02_Hex_Geometry\Results. Relevant output for the present case comprises:

 

•Ex_009_geom.geo file containing the geometry and mesh in ParaGeo format

•Ex_009_geom.GeoSumm file containing the summary of the geometry in ASCII format. Note how in contrast to the conversion type "GROUP" used in HEX modelling applications all the geometry sets (e.g. the boundaries) contain surfaces rather than nodes as shown below.
