Symmetry in CHT problem
 
Good morning,

I am trying to model a half - symmetric CHT problem with one fluid domain and multiple solid domains.

Do I have to make multiple symmetric boundary conditions (1 for the fluid domain and one for every other solid domains) ?

When i set total source power for the solid subdomains do i have to input the real power or just half of it because the half symmetry of the model ?

Thank you in advance,

Input half the power.
You'll need 1 symmetry boundary per domain, but if your solids are all the same material you can group them into 1 domain.

Thanks !

I will probably model the domains separately as i need to input different powers in each.
