Hello all.

Please can anyone tell me what is this message and what can I do about it?

Thank you in advance.

Best regards

I have no idea what that means.

So you need to debug this as you do for any inexplicable error message - simply your model until it runs. Then add the complex bits one at a time until you identify which bit is causing the error. Then at least you know where to look.

Thank you ghorrocks for reply. I solved the problem by simple deleting all domains and interfaces and nemed them simply (1,2,...). And it works now.

So thanks again

If you search in the documentation for convert_name_u2s, you will find the following

18.5.3.1. CONVERT_NAME_U2S

Converts user names to solver names, for domains, subdomains, boundary conditions, materials, phases and variables. It is available in both user CEL and junction box routines.

Since you worked around your problem by renaming your domain, interfaces, etc, it seems one of the previous names caused some internal problems when converting them (convert_name_u2s_INT)

Hope the above helps,
