Region used for material orientation assignment can also be used in meshing a part. Here is an example of messing a part using C3D8R element.
Some Python codes for build Region in Abaqus are really difficult to figure out although Abaqus has a lot of examples and detailed manual and reference. Here is an example for creating discrete material orientation using Python script.
有时候只能在没有图形界面的情况下运行 Abaqus，比如在某些高性能计算集群中，又或者仅仅是为了能够通过 Python 批量运行模拟并获取结果等。
In Abaqus, there is an Abaqus Scripting Interface to control Abaqus/CAE models and analysis jobs. The programming language Python is used for the script. This feature is detailed in Abaqus Scripting User’s Guide. Here is a simple but fair detail and completed explanation on the basic rule for Python language.
