Dear all,

Im performing Fluid-structure interaction as coupling of the Fluent and Mechanical solvers.

This way, I got multiple coupling iterations during one timestep, i.e. multiple Fluent solving during a single timestep.

However, in my model I need to use also an UDF at_end and cgmotion, which I was using previously only during a standalone Fluent calculations. Therefore my questions arises, how these UDFs will work when there are many coupling iterations per timestep? I mean, I'm asking if the UDF at_end and cgmotion will be runned during every coupling iteration, or just during only last coupling iteration? I strongly preferr the latter option

Kind regards

I believe the UDF will be run every coupling iteration.
