Are there any manuals? How do I learn the programs?
The programs contain comments to direct users. In addition, the reference book explains some of the programs in greater detail.
Are the programs fully featured? Do they have any restrictions?
All programs are fully featured. There are no programs with limited use. However, you are not permitted to decompile any programs.
Why not require the programs to have a license key to operate?

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.
