Membranes are used to analyze the behavior of small substances, to simulate transport processes, to study the structure of macromolecules or for illustrative purposes. They can be generated in several ways: The problem will be formulated as the Membrane Packing Problem. It will be shown that the theoretical problem of placing proteins and lipids onto a membrane area differ significantly. Then different partly historical membrane modeling methods will be introduced. Membrane modeling tools will be evaluated which are able to semi automatically generate these model membranes and thus, drastically accelerate and simplify the membrane generation process.
