You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: DEMO_aorta_build_passive_01.m
    path of file: ./repos/GIBBON/docs
    
    the code of the file until where you have to start completion: %% DEMO_aorta_build_passive_01
% Below is a demonstration for:
% 
% * Building geometry for a subject-specific aorta
% * Creating the FEA mesh
% * Coding the abaqus structure

%% Keywords
%
% * ABAQUS
% * aorta
% * hexahedral elements, hex8
