Hi [name removed],

a lot of people have already written on that topic and I found a lot of examples. I’ve tried to adapt them to my case but it is still not working.

I would like to vary waves in time in the boundary limit.

You can find the files in attachment. The error message is a segmentation fault SIGSEGV.

I will be very pleased if some can help me or provide me a case (with all the files) which is working.

Best regards

Hello

Which version of tomawac are you using ? the number of your arguments of your limwac corresponds to a V7P2 version, that will make a problem if you are using V7P3

Hope it helps.

I’m using V7P2.

Hello [name removed]

I made it work with your case with V7P2 here it is.

Some comments :

- 50 Iterations for source terms is far too much you make a lot of calculations for nothing. It should be less than 5

- Do not comment USE INTERFACE\_TOMAWAC, EX\_LIMWAC =\> LIMWAC

It will help you to know if you made an error in your interface

Thank you very much. With your [name removed] it is working. I don’t understand Fortran which is quite a problem.

And also thank you for the advice.
