Hello, I'd like to expand my knowledge about fixtures in FEM with some good literature or examples. In many cases, there are different ways, you can solve a problem with several fixtures wich even let the results vary a lot. Since line fixtures do not exist in reality, I'd like to have a better understanding how to create fixtures as close to reality as possible.

Does anyone know some good literature, skripts/information or even a good knowledge base in the internet? In english it would be great, even I'd prefer german since its a little bit easier.

With special greetings

Wolfgang
