Copy failed: [Errno 2] No such file or directory: 'C:/.../output.resu.med'

BGS

I don't know what I am supposed to do about this error. Everything seemingly works if I skip the output. If I include output I get an error like the title but the directory that is referenced is created by running the case. In output I define output.resu.med location at same level as hdf file and the name I use there is used when run the case. Running case creates other folders and files (so I don't think a permission error is the cause). Anybody have any idea what the problem might be?

Thanks for any help (I have also attached mesh and comm)

Hello,

MECA_STATIQUE => linear STATIC operator, no time inside (except when you use temperature to compute thermal strain)

Hello AsterO'dactyle,

thanks for your reply. I have updated this but it is not the solution (I had created already with nothing selected there).

Maybe I should've said that the output.resu.med copy failed occurred at the ...\RunCase_#\Result-Stage_1\output.resu.med location if that wasn't clear from context.

Kind regards.

Hello,

CHAM_MATER in MECA_STATIQUE ?
If there's an error in your input file, either not caught by the parser or explicitly (this is rare, but it happens). It may well display MECA_STATIQUE command but save nothing at the end. This is particularly the case if you're on a Windows version.

I have both included and excluded CHAM_MATER (and AFFE_MATERIU) but that doesn't seem to matter.

I probably should've mentioned explicitly mentioned CodeAsterForWindows.

Thanks again so much for your reply, AsterO'dactyle.

Thanks for you reply miib 🙂

I don't think that is the problem. I am using a work computer and the path is just like:

C:\Users\usr\Documents\CodeAsterForWindows...No...Spaces...Or...Special...Characters\ProjectFolder\file.hdf

and then in this project folder other folders/files are created.

The only thing I can think of in this vein is that I have two work account names, like short and Full Name but when I click the path it shows short.

Thanks again for the reply miib 🙂

Also, I have run complete examples that work (I have .med and .comm) and some of those seem to work, so it is definitely something I have done wrong. I would hope that I can follow the comm file examples I have (maybe not).

BGS

I have seemingly sorted this out. Probably very obvious that I am using code-aster for the first time and just trying to setup a very simplified version of what I want to model. I think I just updated the comm file a bit, changed how I was doing mesh (in comm that is) and the boundary conditions. I am not quite sure why that influenced the output file except that some errors got through and it was just showing up in this Copy failed message.

Thanks again for you replies AsterO'dactyle and miib 🙂

Also, I am sorry but I am seemingly unable to edit the title to add [SOLVED]. Maybe because I have already edited the original post?

Hello BGS,

I started calculation with your Stage_1.comm and CableMesh.med and get an error after MECA_STATIQUE started (I copied this from terminal)

This error is not in .mess file. Just in last line in mess file is:

<I>_EXIT_CODE = 1

So I changed MECA_STATIQUE to:

reslin = MECA_STATIQUE(CHAM_MATER=fieldmat, CARA_ELEM=elemprop, EXCIT=(_F(CHARGE=FixedNodes), _F(CHARGE=LoadMidNode), _F(CHARGE=Gravity)), INST=10.0, MODELE=model)

then I rerun calculation, and get another error after MECA_STATIQUE:

Le système linéaire à résoudre a 12015 degrés de liberté:
- 12003 sont des degrés de liberté physiques
(ils sont portés par 4001 noeuds du maillage)
- 12 sont les couples de paramètres de Lagrange associés aux 6 relations linéaires dualisées. La matrice est de taille 12015 équations. Elle contient 60060 termes non nuls si elle est symétrique et 108105 termes non nuls si elle n'est pas symétrique. Soit un taux de remplissage de 0.075 %.

this error is in .mess file too.

So there is something wrong with model.
It is a straight line 4000 segments long. Segments are modeled like BARRE. I don't now much about BARRE but from test cases, it is used for cable in prestressed beton with just axial force in segment. Every end of a segment should by somehow supported.

With BARRE and MECA_STATIQUE you can do something like this:

With LoadMidNode in Y direction and Gravity in Z direction maybe you can use MODELISATION=POU_D_E?

P.S. In gravity there is:
DIRECTION=(0.0, 0.0, g),
g is obviously typo error maybe like this?:
DIRECTION=(0.0, 0.0, -1.),

So I think that first error:
Copy failed: [Errno 2] No such file or directory: 'C:/.../output.resu.med'
is printed because calculation stopped with error and there are no outputs.

Thanks for your reply Stanislav,

Yes I modeled with POU and yes the gravity was supposed to be 0,0,-1 and this all worked. I am just using this for the first time and there were some other setup errors that I fixed and was able to run.

Thanks, for your input 🙂 I am not sure why I am unable to edit the original post to set as solved.
