CFX Initial Values file error
 
Hello,

Does any body know about the meaning of Global Error stated below?
-----------------------------------------
Global Error: In Analysis 'Flow Analysis 1' - Domain 'Default Domain': Transient analyses require that initial conditions are specified unless an Initial Values file is specified at run-time.


Global Error:
In Analysis 'Flow Analysis 1' - Output Control: No intermediate transient results files have been defined.

Yep. It means that Transient analyses require:
1) that initial conditions are specified
or
2) unless an Initial Values file is specified


The second part says that you are not saving any intermediate result files.

Hello
Thanks but where I have to specify the initial condition for transient analysis?
for second error, which type of file I need and how to use it?

You must either specify initial values or use a previous results file as initial condition. Initial conditions can be set under Default domain/initialization, or using Insert -> Global initialization. If you want to use another file as initial condition, specify it before starting the solver.

This is well covered in the manuals, see for example tutorial 6 on how to set up a transient analysis.
