Tet meshing is based on tetgen. TetGen requires a interior points for regions to be meshed, as well as intertior points for holes.

meshView(meshOutput);
Build insole
The insole is created by taking the 2D convex hull of the foot (ignoring the z-direction). Next this convex hull is resampled and filled with triangular elements. The z-coordinates are then based on the nearest foot nodes. The z-coordinate data is next smoothed to create a smooth surface. This surface is next thickened to form hexahedral elements.

Quick viewing of the FEBio input file structure
The febView function can be used to view the xml structure in a MATLAB figure window.
febView(febio_spec); %Viewing the febio file
Exporting the FEBio input file
Exporting the febio_spec structure to an FEBio input file is done using the febioStruct2xml function.
febioStruct2xml(febio_spec,febioFebFileName); %Exporting to file and domNode
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='internal';%'internal'; [runFlag]=runMonitorFEBio(febioAnalysis);%START FEBio NOW!!!!!!!!
