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_febio_0050_foot_insole_01.m
    path of file: ./repos/GIBBON/docs
    
    the code of the file until where you have to start completion: %% DEMO_febio_0050_foot_insole_01
% Below is a demonstration for:
%
% * Building triangulated surface geometry for a foot
% * Meshing the foot using tetrahedral elements
% * Building surface model of an insole and meshing it with quads
% * Extruding the surface to a thickened layer of hexahedral elements
% * Defining the boundary conditions
% * Coding the febio structure
% * Running the model
% * Importing and visualizing results

%% Keywords
%
% * febio_spec version 4.0
% * febio, FEBio
% * shoe insole
% * contact, sliding, friction
% * tetrahedral elements, tet4
% * hexahedral elements, hex8
% * static, solid

%% Running the FEBio analysis
% To run the analysis defined by the created FEBio input file the
% |runMonitorFEBio| function is used. The input for this function is a
% structure defining job settings e.g. the FEBio input file name. The
% optional output runFlag informs the user if the analysis was run
% succesfully.

febioAnalysis.run_filename=febioFebFileName; %The input file name
febioAnalysis.run_logname=febioLogFileName; %The name for the log file
febioAnalysis.disp_on=1; %Display information on the command window
febioAnalysis.runMode=runMode;

    %% Exporting the FEBio input file
    % Exporting the febio_spec structure to an FEBio input file is done using
    % the |febioStruct2xml| function.
