Does anyone know what the default normalization of the eigensolutions in COMSOL is. I would like the normalization conditions intop1(abs(u)^2) = 1 but I am not sure how to achieve this. I have tried to define an integral operator do investigate the normalization but I get an error. Is there any easy way to get the desired normalization? My script is attached below.

Hi,

You cannot create your own eigenvector scaling. You can only choose between the three built-in scales as shown in the attached screenshot. The default is to set the RMS of all degree of freedom values to 1.
