Hi all,

I am working on thermal distributions of 3d glass mould equipments and I solved it ''pressure-coupling'' as I selected ''simple'' not ''PISO'' and all other remainings is First order upwind scheme ( whenever I choose 2nd order scheme divergence from temperature ... )

Anyway however it was solved by as I wrote above. I was upset to all residual behaviours.

The pic is attached. It behaved like trasient following about 1000 iterations

Kind Regards,
