Hello everyone,
I´m new to numeca/Fine and doing a study with the UQ-module in Design3D on a turbine row with Stator/Rotor geometries. I have parametrized the Stator with autoblade and want to combine the grids with a multistage script in Design3D. The Script combines Stator and Rotor grids and works fine when exeuted manually. However running the Design3D chain, there is a problem generating the grid-file for multistage and the solver crashes.

I also get an error in "job_igg_multistage":

Can anyone help me where to find the problem?

I have encountered similar problems and work for many weeks to figure out. This is a strange problem in Numeca, I guess. The manually meshing does not give any error but one can have an error when the same is generated through the interface of Desing3D.

I would suggest you that the template .trb should be of a high-quality mesh. pay attention to min. skewness, aspect ration and span angular deviation. and the parametric model from which you generated .trb should be of the minimum number of sections. there is no solid argument in favor of these considerations. I did not use UQ module though.

Dear Tim,

let me first summarize the situation as I understand it:

• You built a multi-stage script for AutoBlade following the instructions in the manual. This works fine.
• Then you built a script for meshing with AutoGrid5, which you import under 'Mesh Generation'

• When you start this script outside of FINE/Design3D it runs and generates the mesh successfully (It most likely opens the GUI of AutoGrid5)
• When you run the same script now through FINE/Design3D you get the error message of the meshing job: "STARTUP_ERROR: Cannot Access Display itsm-numerik417:0.0 from itsm-numerik417"

It seems to me that the underlying problem is related to the environment variable DISPLAY.

• In your case, echo $DISPLAY will return itsm-numerik417:0.0, which is the name of your machine and the number of the display. This should be equivalent to :0.0.
• However, we have observed that in some cases a display such as itsm-numerik417:0.0, prevents the starting of GUI's. If this is the case, you cannot open, for example, xcalc neither
• The problem comes from the environment, but impacts some of our software

What can you do to get your job running:
If you built your meshing script yourself and if it opens a GUI of AutoGrid5, in case that you run it outside FINE/Design3D, you can add a flag for batch mode to the start command of AutoGrid5[*]-real-batch -autogrid5[*]In this case no GUI will be opened[*]Please note that you might encounter a similar problem with CFView for the post-processing. Here, however, we need to open the GUI, there is no batch mode. [*]The next release version of FINE 13.2 will come with a solution for this DISPLAY problem also for CFView, where we modify the start command.[/LIST][LIST=1]

There is a possible second workaround (but not recommended for AutoGrid5, only for CFView), that sometimes works

• From user's side it is possible to connect to the local host with ssh and display forwarding:
• 1. Terminate running pvm
• > killall pvmd
• 2. Connect to the local host using ssh
• > ssh -X user@hostname
• 3. launch fine: display will be automatically set to localhost:10.x
• > printenv DISPLAY
• DISPLAY=localhost:10.0

Best regards,
Dirk

Hello everyone,

@dwunsch: Many thanks for your reply. It really helped me to get my project running. Your solution with connecting to localhost with ssh solved the problem after some issues with the local network.

Currently the Design3D Chain is running and all tasks finish with the computation. I get all the deterministic results for the defined collocation points. However I have the problem, that the Non Deterministic Results in the Uncertainties Monitor are not displayed correctly.
In the project folder, there is a .ssd file which I think is the problem. Example:

Number_of_quantities 0
Number_of_uncertainties 2

.uq file same

It seems like there are no quantities defined for the Non Deterministic Results. A section in the User manual notes, that the selected Quantities in the Post processing page are not used in the non deterministic post processing.
How do I set up the Quantities for the non deteministic post processing? The run File doesn´t show anything.

Many Thanks,
Tim
