I am working with a reactor vessel in ANSYS Fluent. There is a core inside the vessel.

When I try to mesh the total geometry with the default settings I get the errors as shown in the photos. How to solve these errors?

Also I want to simulate the vessel with three different porosity values (upper tube unit, reactor core and bottom part of the vessel) with a pressure source and a heat sink. How to do this?

Image shows solid model. Please extract the fluid region in SpaceClaim.

From image it looks like you are using hex dominant method. Please use patch confirming tetrahedorn method.
