Creating model geometry and mesh
A box is created with tri-linear hexahedral (hex8) elements using the hexMeshBox function. The function offers the boundary faces with seperate labels for the top, bottom, left, right, front, and back sides. As such these can be used to define boundary conditions on the exterior.
% Create a box with hexahedral elements beamDimensions=[sampleWidth sampleThickness sampleHeight]; %Dimensions beamElementNumbers=[numElementsWidth numElementsThickness numElementsHeight]; %Number of elements outputStructType=2; %A structure compatible with mesh view [meshStruct]=hexMeshBox(beamDimensions,beamElementNumbers,outputStructType); %Access elements, nodes, and faces from the structure E1=meshStruct.elements; %The elements V1=meshStruct.nodes; %The nodes (vertices) Fb1=meshStruct.facesBoundary; %The boundary faces Cb1=meshStruct.boundaryMarker; %The "colors" or labels for the boundary faces elementMaterialIndices=ones(size(E1,1),1); %Element material indices

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.disp_log_on=1; %Display convergence information in the command window febioAnalysis.runMode=runMode; febioAnalysis.t_check=0.25; %Time for checking log file (dont set too small) febioAnalysis.maxtpi=1e99; %Max analysis time febioAnalysis.maxLogCheckTime=10; %Max log file checking time [runFlag]=runMonitorFEBio(febioAnalysis);%START FEBio NOW!!!!!!!!
