Hello, I’m using v8p3r0 and I want to couple Telemac 2D with Tomawac and Gaia. Firstly, I want to initialize only telemac 2D coupled with Tomawac and then start from a previous computation file to couple Telemac 2D + Tomawac + Gaia. Before coupling with Gaia, I did a test just to restart Telemac 2D coupled with Tomawac and I’m having issues restarting tomawac. I have the error message: LECSUI: BAD NUMBER OF PLANES IN THE PREVIOUS ``` COMPUTATION FILE : 0 FOUND 36 EXPECTED ``` I looked at the example Next\_comput (which is not coupled) and I’m able to launch it. The difference I see between the global files result is that I have a variable “CURRENT-WIND”. CONSIDERATION O A WIND = NO, but in the Telemac 2D cas file, I have activated WAVE DRIVEN CURRENTS. Is it possible to use NEXT COMPUTATION when Telemac is coupled with Tomawac? Thanks in advance for your help, [name removed] ---

Hello You will find an example of start from a previous computation with tomawac and telemac2d coupled in the sisyphe case examples/sisyphe/Littoral\_reprise/ It is a coupling with sisyphe too but you can easily delete the coupling to sisyphe. Hope it helps kind regards ---

Thank you! It was helpful, I was able to fix my problem and it runs perfectly now starting with a previous results file. [name removed]
