#1 Re: Code_Aster usage » OpenTURNS parallel evaluations » 2020-07-09 13:10:38

Hello,

i am interested in the discussion because i am getting more or less the same errors . I do get these errors on Salome Meca 2019. Are you too using the 2019 version too?

#2 Re: Code_Aster usage » Openturns and code_aster » 2020-07-03 09:35:48

I think you can dump the study from the Salome environment and see the OpenTurns part of the code. Now i do not know if that code can be utilized to run a parametric calculation from within ASTK by calling to the OT libraries.

Hello,

i have stumbled upon an old thread talking about MSE approach. The thread can be found here : /viewtopi c.php?id=13987 . I have two questions now, is there a method for multiple bodies in the same mesh ? and if so, which commands are to be used?


Thank you very much!

Hello,

i was trying to run some analyses in ASTK but i encounter the following error.

The version of ASTK i am using is the one found with Salome Meca 2018.


Thank you.

Hello,

i am trying to find a way to create assign meshes and create groups on my models with python. I was looking around for similar threads but found none at the moment. Is it possible?

Hello,

i am performing various modal analyses on some models. I would like to know how to print the Modal base so to see the differences between the analyzed models. Is it possible?

#9 Re: Code_Aster usage » MAC_Modes but with selected modes? » 2020-04-01 08:14:44

Do you know which commands should be used if one  wants to calculate the MAC between specific nodes of the experimental and numerical model?

#10 Re: Code_Aster usage » MAC_Modes but with selected modes? » 2020-03-31 08:28:51

Found a workaround with the command EXTR_MODES to get the modes i need from Calc_Modes.
Any other suggestions are really welcome, thank you!

Hello,

i am trying to define a MAC criterion with the command MAC_ΜΟDES but in my bases i have various modes to confront.
Lets suppose that in the first BASE the modes go from 1 to 6 and in the second base for the MAC the modes are selected and
are 1,2,3,4,9,10. I am getting an error due to the series of the order that doesn't correspond. Is there a way to do this?

Thank you,
Best regards,

Hello,

i am trying to import some libraries to see if i can work with them in CA but i am getting an error which says :

"RuntimeError: module compiled against API version 0xc but this version of numpy is 0xa "

This is done in the 2018 version of Salome Meca. How can i "update" the numpy version? According to the message the analysis gives
i have Version de Python : 2.7.10, Version de NumPy : 1.12.1  .

#14 Re: Code_Aster usage » How can i add rotation DOFs in 3D modelization? » 2020-03-05 19:28:59

So i should add DIS_TR to my model with K_TR_D_L and M_TR_D_L? Would you have an example to give me?

Hello,

i would like to ask how is it possible to add DRX,DRY and DRZ while doing a 3D modelization.
I know that 3D means that the elements only have DX,DY,DZ but i would like to enrich my elements to have also rotational dofs!
Is it possible?If it is how?

Hello,

i am trying to understand how to import into OT module variables and .npy files from a text stage command. I need the .comm file to be in text due to some
python scripting i have added. Do you know a way to make the variables and .npy files produced by the study to be imported or seen in the OT module??

#19 Re: Salome-Meca usage » Compound philosophy?! » 2020-02-29 15:12:08

When you don't merge the nodes, when a liaison_mail contact condition is stabilized you define every interface (master & slave) or can you do it for volumes?

Hello,

i have some problems making my model run an analysis. This is probably due to the fact that the model is composed
of many pieces. I have tried different ways of making it work and would like to know how do you work around on a study
with many pieces.
The ways of my tries where, partition the geometry and create a mesh whereas i have already defined groups from geometry.
The second way was to compound but i found some problems with LIAISON_MAIL, i don't think that with many pieces it is wise to use, or at least
if it to be used with many pieces i am using it badly.
The third way was to see if the model could work by boolean fusing the solids together. It did in fact work, although i couldnt get the necessary groups
out of it.
Do you have alternative solutions?

I have a model that i can import in Salome Meca 2019, is it preferable to import it in .step or .brep format?

#23 Re: Code_Aster usage » What is the best strategy to follow when you have many LIASON_MAIL? » 2020-02-24 16:44:18

Hello,

my problem is that i have a little too many adjacent volumes in place for an analysis with many different material properties.
I revisited my model and saw that some geometry components where missing, this was corrected and the meshing procedure went good.
Now the problem i am facing is that even if all the geometry is there, it doesn't seem to "merge"  and so i get coredump analysis errors
or due to the fact that i am using CALC_MODES command as a test i get the message that says to utilize something other than PLUS_PETITE,
like the option BANDE which probably means that something is in the air flying somewhere.
I attach a .mess file for further info and insight!

Hello,

in my study i have a model composed of many pieces. More than 100 pieces. I imported those pieces from
a step file, cleaned them, repaired them and meshed them without problems. Now i make a compound to
get the whole model going but i encounter some problems, first is that in the compound merge, if the
tolerance is high i get a mesh jacobian error, if the tolerance is low i get negative frequencies in my 
modal analysis. How do you resolve problems like these?

#25 Re: Code_Aster usage » What is the best strategy to follow when you have many LIASON_MAIL? » 2020-02-21 19:33:22

Hello i noticed some inconsistencies with my model. This error could be result of those inconsistencies. I am correcting them now and
will report back here if the error comes up again.
