AVwin98: code check results

[Subject Prev][Subject Next][Thread Prev][Thread Next]
We ran your example with the same free AVwin Plus version that was
downloaded from the web page and we got 0.48
stress ratio with first order analysis and 0.97 with second order analysis.
The 0.48 value is very close to the 0.47 value given by the other programs
that you mention.

Apparently you are comparing the results between two different types of
