CFX-Solver hatası

morvinn · September 17, 2018, 09:37

The ANSYS CFX solver exited with return code 1. No results file has been created.

why is it give like that error you think ?

Many, many things cause this. CFX error messages are renowned for not being very helpful. You have to look at the error in context to work out what it actually means.

more detail.

+--------------------------------------------------------------------+
| Checking for Isolated Fluid Regions |
+--------------------------------------------------------------------+

3 isolated fluid regions were found in domain Default Domain

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".

That error message pretty much explains the problem, doesn't it?

is that error about CFX-Pre ?

The error says that you have 3 isolated volumes. You need to go back to pre and make sure you connect them using interfaces. Or, if you don't want/need interfaces, go back to your CAD and make sure you get 1 fluid volume.

Once the ANSYS CFX software stop, you should be able to visualize the "Isolated Volumes" in CFD-Post.

Then, you can see where the domain interfaces are missing if needed at all.
