Description: I am working on setting up DOE using LS dyna interface in hypermesh, and wanted to solve using the LS dyna solver. However, I am not able to access to that particular solver
Product/Topic Name : Hypermesh 25/ DOE
hi, have you registered your solver script properly before going to launch execution?
You should register a ,bat file with your solver batch file.

I tried it using
I am inputting this at my location: ls-dyna_smp_s_R12.2.2.0_18-g35eb1fd6fb_winx64_ifort170\ls-dyna_smp_s_R12.2.2.0_18-g35eb1fd6fb_winx64_ifort170.exe from local desktop and then selecting solver as Dyna
Still shows error
you should use the generic solver, not access.
under user arguments, you should probably adjust your inputs. probably i=${file}
Hi @Adriano_Koga
I've managed to successfully submit runs to the server using a batch file, and the simulations on the server are completing without issues. However, I'm encountering a problem where HyperMesh shows each run as failed, even though they are completed on the server.
After checking the directories, I found that HyperMesh is attempting to create and access DOE run folders under:
C:\Users\mkumar6\AppData\Local\Temp\approaches\
However, the actual input and batch files are located on a network drive, which is correctly used for the server-side runs.
I'd like to know:How can I change the default working directory where HyperMesh creates DOE run folders, so it points to the network drive instead of the local C drive?
Design Explorer is going to use the study path provided at the very beginning to define where all the files will be written.
It is going to create a bunch of folder, and for the DOE, it will create a folder named DOE_1, for example.
Inside DOE_1 you will have a few folders named Run_XXXXX, and inside them m_1, m_2, …
you Dyna models are written inside each m_1 folder, and DE will call your solver script from these folders.
So, in the background, DE will change dir (CD) to your m_1 folder of each run and from there call your script/executable. If you want to use your network folder for that, you should create the study at this location at the beginning.
Usually what i try to do to make sure the script is working properly, I always create a bat file that will execute my commands, even if it is a single executable. In order to make sure it will work, I go to the m_1 folder, and making sure there is a .k file, and then I execute the script from there. If the script works fine, then just use it in DE.

Thanks @Adriano_Koga
It worked, however, I'm facing one issue. I have changed the directory and submitting the run through server. On server, all my DOE runs got completed however, in the hypermesh window, it's showing as failed.
hard to tell, but you should probably wrap a batch script to submit your runs, and make sure the script waits until your run is finished before "releasing" control back to design explorer.
I am using design explorer for ls dyna and I am also facing similar issue.
1.I want to run the simulation on remote desktop that situated at the other location. In this case whether i need to use the solver scripts??
Currently I am trying option of "writing solver files only " and running the simulation on remote desktop. But after simulation completed design explorer not extracting the results. Showing error of report not found.
so, to solve this issue report generated using the Hyperstudy now results extracted but showing some different values.(9999.99)
@adriano_koga please can you help me with this
