hello to all the salomeans,
It's been a few months since the lastq time I wrote on the forum and I think you still thank the sky for it.
Unfortunately the pacchia cannot last forever:tongue:.
today, so much to make you play with something, after about a week that I resumed "work" with the meca salome (I don't tell you what enterprise to install a working copy on ubuntu) I began to have the first hitches.
despite the internet searches I didn't finish much.
I put the facts to you.
After modeling a church, I am going for degrees to do analysis of the structure, first with static linear analysis of the entire monomaterial complex and then attributing the materials to increasingly large portions of building, until arriving (one day if everything is okay) to the whole complex with all the diversified materials.
then I will pass to static non-linear analysis, modal analysis etc....
but already I've jammed, as I said:
with a portion of multi-material aisle, created the calculation code, the .mess tells me that it does not find the slave surfaces (the masters yes), the beautiful is that if I try to move them to master me find them.
I am getting rid of a day, looking on all forums, but the language does not help me and so I humbly ask for help to you compaesani.
I attach the mess file and an image of the structure, I cannot attach it for work reasons but also of heaviness.

By the way, spulcianod the code-aster manuals I read (but maybe I understood wrong) of some commands that allow the creation of slots on model 3d, but I understood well or did not understand us a h? no because in case for me it would be very useful to learn how to use these commands.

quick answer:

1) Are escalve mailles elements 2d? must be if the maizes are 3d

2) I usually make a liaison mail for each connection, you have put so many maitres and many exclaves inside the same command, how does the code to understand who goes coupled with who?

3) the error that gives you the code seems more tied to the fact that there option affe_maillage is not extended to the whole solid. I saw you have so many mesh 3d in your tree, did you make a compund of these mesh before feeding them to code_aster? The compound can also do it in aster using the commando axle_maillage but I think it's easier to do it in salome.

Bye.

However, if you know a minimum of English, www.code-aster.org It's the right place for you.

save hunter, you are an anchor of salvation, every time you come and take off me, thank you endless:finger:.
I try to answer point by point.
1) the slaps are prphatically identical to those masters, in the sense that if above a harco I have a brake, the forces that exchange act on the same surface of contact between the two elements, then if there is a diference of coding of the elements from 2d and 3d nn I understood it, for me the contact surface brake arc is cmq, for both elements, a flat but of shape.
2) with regard to the relationship between slave and master, I had also thought of it that it was the case to do it for every combination of exchange, but as for example previously made it had not created problems to put them in two unique macrosets I hoped that it could work (on an entire church there is to kill to make all the combinations!).
3) I press that I meshato solids in autocad, exported to sat, converted into open brep in salome and meshati separately, each element is in function of the material that composes it.
then solid meshati joined them with a compound making them make submesh composed by individual volumes and surfaces shiavo/padrone, constraints and loads.
in fact the mesh slice is the compound of those above.
As for the command affe-maillage, rechecking the calculation code, I noticed that I did not put it:tongue: Now I try to use it and see how it goes, then I let you know if everything's okay.

Thank you very much, I think one day I'll have to get rid of myself.

just an update:
I created the combinations in liaison_mail, but it did not create effects, then I tried to search for the command affe_maillage, but I did not find it, so I thought you went to memory and you meant asse_maillage, but as you said it serves to make a pseudo compound such, if instead you meant the command affe_confes templatee l'I applcicato all the model, it is for that I do not understand the material.
I try to ask also on the codeaster forum

You're right, I meant models, but I think you used it.

I apologize if I still bother (I posted the topic on the code-aster site but still things are not clear to me) I wanted to ask another thing.
I searched the web long and wide but still I did not understand, what are the dkt?
I realized they're surfaces, but what kind?

 

[UL80]

Now I know they are, are the meshate surfaces according to kirchoff (more or less)

viene kirchoff in persona a meshartele?

should be shell elements.

Bye.

 

[UL80]

Now me and kirchoff are ass and shirt:tongue:
But one thing is not clear to me, the aster divides the elements of the liaison in solids and coques (shells or surfaces) and the various slave combinations master among these elements.
Now the question is this, let's have a pillar that affects another solid, then I for liaison go to consider only the surfaces (creating subgroups) only the surfaces of these two solids that come into contact, so these surfaces consider them as solid because they are part of solids or consider them coque because once removed from solids are simple surfaces?
I think they are massif, but if you let me down tonight I sleep quietly:biggrin:

 

[UL80]

is metto in group_ma_matri solidi e in group_ma_escl the surface area su cui incidono, the supp. suddetta me la trova ma mi dà errore di cui in allegato, se invece di group_ma_escl metto mét_escl allora la sup. Not the trova nemmeno. :36_1_4:
no posso più non ci sto a capì un h.sono giorni che cerco sul web e nonosante tutto ciò che ottengo oltre ai mal di testa paurosi sono mille dubbi su ogni comando che vado ad usare. perchè non fanno una guida in grzia di dio?

siccome non riesco a mistre l'allegato allora:
