Hello guys,

I am facing a problem when i try to perform a JetA oxidation in a geometry which i design as a combustion chamber. to perform the combustion im using the eddy disipation model, and i am using JetA Air WD1 and Jet Oxygen WD1 as reactions.

the error which i get when i try to get the results is shown below:

An error has occurred in cfx5solve:

The ANSYS CFX solver exited with return code 1.

And if i try again it says that its a problem of my mesh.

enclosed you can find my geometry design, where i created two parts (fluid and solid).


To specify more, i also should say that due to i need two diferent boundaries to create my inlet (fuel and air), i create two diferent fluid cilinders that are connected between each other as an unique fluid.

when i get my results i also get

" If the isolated regions do not have the pressure level set either
by the boundary conditions or using a reference pressure equation,
you may encounter severe robustness problems.

This situation may have arisen because a domain interface was not
properly defined during problem setup. Please carefully check
the setup.

The solver will stop now and write a results file. The isolated
regions can be visualised in CFX Post by making plots of the
variable "Isolated Volumes".

If you are sure that the pressure level is set in each isolated
fluid region then you can force the solver to turn off this check
by setting the expert parameter "check isolated regions = f"."
