Why are all modules now free?
As a courtesy, ESP Composites offers the modules to assist both students and practicing engineers during the learning process and for use in their work efforts. There are no usage restrictions, but you must agreee to the Terms of Agreement are in effect. At a later date, it is anticipated that the modules will be fully unlocked so the VBA is accessile.
Are the programs accurate and will they work on every computer?
All programs are tested to comply with various known solutions. The programs work on the vast majority of computers. However, there are some configurations that may not be compatible. Please report any errors or bugs.
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 must adhere to the Terms of Agreement. You are not permitted to decompile any programs to view the VBA source code. At a later date, all programs will be free and the VBA will also be accessible (not currently accessible).
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. 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.
