Hi evryone. I'm new in comsol. I'm a student of master degree .. option Physics and radiation technologies. I want to simulate the thermal stress of fuel rod in triga nuclear reactor. I have a little problem with materials overlapping in the red cercles (image attached). its dosen't make sense becauce those solid materials are tough .. I want to simulate the thermal stress in those materials and I have a helium gas between them. so I need your help. if something I should know please tell me. https://imgur.com/a/5kAlSNr

Are you sure you have set the scaling factor in the deformation plot correctly? By default it may be set to automatic scaling which may result in a high value just to make small deformations visible. Set it to 1 for real deformation.

Cheers Edgar

Thanks sir Edgar , I already had the same problem but after I set the scaling factor to 1 it's work for me .
