Q: For Beam program, do I need to input exact E & I value?

A: No need if the EI is constant throughout the problem and the deflection is not desired. Otherwise, you need to define exactly.

Q: Why does the Beam program sometimes give inconsistent results?

A: In extreme circumstances, the results may be incorrect due to truncate errors during matrix inversion. If a number of beam spans were defined and there is significant stiffeness difference (EI/L) among the spans, the error is accumulated during the solution process. The default moment of inertia (I) for beam sections is 1.0, adjust this value may eliminate the errors. Another reason might be that the number of element divisions is too small (it is done automatically by the program). Manully divide the beam section into two will solve the problem. As we have all learnt in the school, more elements usually lead to more accurate finite element results.

Q: Can the graphics of the output be transferred to programs such as MS Word?

A: Not directly. But user can copy the graphics to these programs by screen shots. Here is how to do it: 1) Place output graphics in the center of the screen, 2) Press “PrtSc” key, 3) Click “Start” -> “Programs” -> Accessories -> “Paint”, 4) Press “CTRL + V” to paste the screen into MS Paint, 5) Cut the portion of the picture that you are interested in to documents in programs such as MS Word, MS Excel, MS Powerpoint, etc.

Q: Do you have any guarantee for the programs?

A: We do not provide any guarantee for the programs. However, if you are not satisfied for the products, you can fax us a signed affidavit within 30 days of purchase, indicating the reasons and declaring that you have destroyed all the programs, we will refund your money.

Q: How long will it take for the programs to be delivered after payment?

A: We need 2 to 3 business days to process each order and send the programs by email.

Q: Do you accept credit card by fax or by telephone?

A: Not by telephone. But we can accept credit cards through our secured online payment processing website.

Q: Can you provide detailed documentation of the programs?

A: The help text that comes with the programs contains basic information to run the programs. Licensed users will received improved version of the help documents. The theories behind most of our programs are very basic. Our examples contained in the package are taken from references widely available. Users are required to verify the results before use.

Q: How do users obtain updated versions?

A: We will send the updated programs to licensed users free of charge if the revisions are mainly for corrections of program bugs and typographical errors. Users have to buy a new program if the revisions are made for improved or added functionalities.

Q: Do you have metric versions of the programs?

A: Most of our programs are non-dimensional. User can choose any units for dimensions, forces and other parameters as long as they are consistent with each other. User needs to interpret the output results accordingly. The units will be noted in the output. Some of the programs are English only. Their metric versions are under development. We will send the metric version to licensed users free of charge when they become available.

Q:Dou you have any guarantee for the programs?
