Hi,
When running sediment transport in a bend, I found that the secondary flow correction works when Sisyphe is DEcoupled with Telemac2D (version 6.1). However, when I ran Sisyphe coupled with Telemac, the secondary flow correction does not work. In the coupled mode, it doesn't matter if SECONDARY CURRENTS is set to YES or NO, the results are identical (and bad).
My guess would be that in the coupled mode the secondary flow subroutine is probable not been read.
I hope you fix it soon!
