Optimization failed

[Mr. Christoph Schmotz 0]

Hello!

 

I wanted to create a new optimization using the Sobol-Tool. I followed the instructions from the Tutorial but I think, I missed something. When the prozess finished, all of my resutlts failed because the evaluation of my two variables showed "NaN". See the attached screenshot. I evaluated these values but still did not work. I created a new optimization, did not work.

 

Maybe someone had the same problem and can help me?

 

Thanks

Christoph

Hello Christoph,

 

apparently you forgot to attach the screenshot, which would be very helpfull to understand what the problem is.

Or maybe you can upload your caeses file?

 

Regards,

Simon

Oh, sorry. Here is the screenshot.

[Mr. Carsten Fuetterer 9]

Hi Christoph,

 

can you post one of the stdouterroroutput.redirect files, which are located in the design directories.

 

Did you run the baseline first? Did you got your objectives? Can you find any results in the design directories?

 

best regards

 

Carsten

[Mr. Christoph Schmotz 0]

Hi Carsten,

 

yes, I ran the baseline, I got objectives and I am able to find result files.

 

Attached you can see my tdouterroroutput.redirect file.

 

So I cannot upload this kind of file, I inserted it here.

cp: cannot stat ‘../baseCase/constant/polyMesh’: No such file or directory

This is the line which is causing the errors which are appearing afterwards.

The path "basecase" seems to be wrong. But without having seen the project file it is really hard to help further.

 

Can you upload the project file. It would help to identify the problem.

 

Cheers,

 

Karsten

[Mr. Carsten Fuetterer 9]

Hi Christop,

 

could you at least post or send us the shell script? It seams to me that you are not meshing.

best regards

 

Carsten

[Mr. Christoph Schmotz 0]

Yes, I already recognized, that I was not meshing. For faster computation I put the mesh in a seperate folder, so the meshing wasn't done every time. I forgot to change this for the optimization.

[Mr. Carsten Fuetterer 9]

ok in that file are no signifcant errors. Did the solver run?

[Mr. Christoph Schmotz 0]

yes, the solver ran, then the parameters for evaluation were pending a long time, till they all got nan.

Hi Christoph,

 

This problem is resolved now as far as I know (it was a small bug in CAESES). Thanks for your input!

 

Cheers
