Symmetry in CHT problemGood 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, Costin Ruja |

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. |
