At present I am using Comsol 5.3. I have to use a weak expression written as : test(psi)*phi_source+test(p)*usource, in the version 4.3b. By using this expression in my model, which is in 5.3 ,I am getting error. Please tell me how to write this expression in version 5.3.

Hi,

There should not be a difference as such in the way you express a weak contribution, so the problem is likely to be elsewhere. What is the error message?

Regards,
Henrik
