Hi,


I'm trying to replicate a dynamic mesh that was described in a research paper for a two-roller peristaltic pump, I've included a sketch of the deformation of the geometry and the geometry in general.



The paper states that a UDF was used to recalculate the boundaries of the mesh at every time step according to a set of equations relating the boundary geometry to the dynamic position of the rollers, but neither the C code for the UDF or the implementation approach were provided.


Any pointers where to get started with tackling this kind of mesh would be much appreciated, I'm relatively new to using Fluent but would like to learn more.



Any input would be much appreciated, thank you in advance.
