1. My first question is regarding meshing. I am trying to create a mesh only with hexaedra through the CFX mesh but i really can't. All i did was to create surface trianges and some prisms initially and then some heaxaedra were created using inflation (found it in manual).
Isa ther a way to have only hexaedra (besides creating them in ansys mechanical and then import geometry)

2. The second question has to do with a problem. I create two attached volumes and I need the one to always have constant temperature. Are there any constraints or boundaries or something like that for a whole volume?

Use the ANSYS meshing app instead of CFX Mesh. CFX Mesh only creates hex elements from an extruded inflation layer, as you noted.

Is this volume a fluid volume? If so, set it to have use the Isothermal heat transfer equation. If it is a solid domain, leave it out of the model and set the fixed temperature on the surfaces that interface with the other domain.
