Hello Rahul,

Hygroscopic swelling is a functionality available in the Structural Mechanics Module and MEMS Module, starting at version 5.1. This blog contains an introduction to it: https://www.comsol.com/blogs/how-to-model-hygroscopic-swelling/ .

Best regards,

Jeff

Respected sir, first of all thank you very much for your kind suggestion, now i have comsol version 5.2. Now i am trying to input the values of moisture content, (delta C) = 0%, 1%, 2% and Temperature (delta T = 0, 20K, 40K) and want to analyse their coupling effect. I am working in solid mechanics module and trying to find out the eigenfrequency of FGM beam. plz reply asap. Thanks/Regards Rahul Singh (PG student)
