Hi Can you send me the stdout so I see the error msg?

Looking at your input file I also suggest to change

BBOXINCR = 1,

and 

PARFFTX = FALSE, 

PARFFTY = FALSE, 

PARFFTT = True,

Let me know if that solves the problem. 

Cheers A

Hi Andy,

 

Hope this email finds you well.

 

I followed instructions in OPAL wiki page and also the steps described in Yves’ thesis to call a python script using SYSTEM function.

 

Opt-pilot works but I directly receive “Unknown exception occurred during simulation run. Continuing, disregarding this simulation..” message. Although .tmpl file and .py script are at the same folder (TEMPLATEDIR) the python script is not present in any simulation file in SIMTMPDIR folder. I assume that’s the reason causing the problem but couldn’t find a way to solve it.

 

May I kindly ask how I can overcome this issue and use the script?

 

Attached please find the reproducer file.

 

Best Regards,

Can

Hi  Can  

you evaluate the objective at  1.0 m and track to 1.0 m. Now OPAL can stop 

at 0.999 m and then the objective is not evaluated. That is what I interpret from

the output. 

 

Put ZSTOP at 1.01 m  and the problem should be solved.

 

Also use powers of 2 for the mesh sizes i.e. 16,32,64. 

 

I suggest to do an quick run with the optimiser using 

10’000 particles 16x16x16 mesh and increase the timestep 

by one order of magnitude. The you need 2 cores per run and 

one run takes only 60 seconds on my laptop. 

 

Lets see if one generation runs on your side.

Hi Andy,

 

Thanks for your reply. 

 

All right I totally misunderstood the usage of REPARTFREQ then.

 

Please find attached zip file including everything.

 

Best,

Can

Dear OPAL Users,

I would like to use the inbuilt multi-objective optimisation of OPAL but I
have encountered a couple of issues and kindly ask for your help.

- Although I define OPTION, REPARTFREQ = 14; to use 14 cores of my PC it
doesn't allow me to use more than 10 which is the default according to the
manual.

 

The REPARTFREQ has nothing to do with the number of cores. So I am confused 

what you are writing here!

 

 

 

- .tmpl and .in files are working if only I use INITIALPOPULATION=1 but
optimisation doesn't end once it is >1. .tmpl commands are given below.

 

Please send us a reproducer, otherwise it is not possible to track down the problem you

have. 

 

 

Thanks Andy
