How does Excel perform finite element analysis?

Excel can act as a pre/post processor to finite element analysis software. For some software programs, the open source solver CalculiX is used. The latest Windows version can be found at bConverged. Note that the Excel modules use a prior version of CalculiX to ensure compatibility. Do not use the latest version in conjunction with the software from ESP Composites.
