Since stars form in molecular clouds, it is rather important to understand the physical processes that drive their evolution. However, molecular clouds are turbulent and irregular which makes comparison between the models and the observations difficult. Inside the molecular clouds, filaments are very often observed. Since these objets are simpler and more geometrical than molecular clouds, comparison between theory and observations is easier for these objects. We have undertaken the numerical modelisation of one of these filaments located in the Monoceros cloud (NGC2264C) and observed at the IRAM 30m telescope. Detailed comparisons between the model and the
observational data both for the density and the velocity fields are presented and discussed.
