——————————————————<\/span><\/strong><\/p>\n Appraoch 1 :<\/p>\n Fully applied shared topology. <\/p>\n I enabled beta option in “General mechanical” and ” Allow thermal variation along shell thickness”. And enabled “Node merge option at edge”.<\/p>\n When i run the model, thermal growth (distribution) across shell element side (through thickness or varying over surface) is not achieved. And expected deformation behaviour towards Y axis is not acheived instead FE model deformed at ceter portion.<\/p>\n Appraoch 2 :<\/p>\n Partial shared topology applied. Only on Shell to shell element connection .<\/p>\n Whereas for other connections used solid to shell element , bonded contact with “MPC” formulation and “Distributed,All direction” config. Initial contacts result checked and found okay. <\/p>\n And enabled “Node merge option at edge”.<\/p>\n I enabled beta option in “General mechanical” and ” Allow thermal variation along shell thickness”.<\/p>\n When i run the model, thermal growth (distribution) across shell element side (through thickness or varying over surface) is not achieved.

I tried in Element orientation with various “Z” directions (-Z and +Z) . But no sucess.<\/p>\n Thank you in advance. Hopefully i would get clarified with your expertise.<\/p>\n Regards<\/p>\n AE<\/p>\n
