I think it is not fare to be rude to somebody that asks a common question (if it is a common question, may be COADE should make an effort to further clarify its "code stress" concept in the manuals). I disagree with the idea that you should not use CAESAR unless you are an expert in code specifications. There are many engineers around that just need understanding materials behaviour or stress analysis, and not necesarily are familiar with code rulings or, worst, with the somehow obscure (for the beginner, of course) "code stress" concept that CAESAR uses everywhere.
