# Normal Mode Analysis pylimer-tools provides a normal mode analysis (NMA) implementation to predict the loss and storage modulus of polymer networks as published in Gusev and Bernhard [[GB24](../../acknowledgements.html.md#id7)]. This is useful for understanding the viscoelastic properties of the network. The corresponding class is [`NormalModeAnalyzer`](../../api/pylimer_tools_cpp.NormalModeAnalyzer.html.md#pylimer_tools_cpp.NormalModeAnalyzer).
