Installing Code-Aster Salome Meca

Choose a channel featured in the header of iMechanica: 

I would like to try Code Aster or Salome Meca FEM on MS-Windows.  The problem for me is that I can't find a document that gives an overview of what each part does. 

I am used to ABAQUS that comes together with "CAE" for creating input files and visualising the results from an "Output DataBase" (ODB).  I have used the ABAQUS solver separate from CAE for some problems that it cannot create (I used Matlab to write the input file) so have no problem with the idea that different bits of code do different things.

Executing Abaqus from Scilab

Choose a channel featured in the header of iMechanica: 
Free Tags: 

I have managed to adjust a material property to get the best fit to the experimental response using fminsearch in MATLAB, but I lost access to free MATLAB so I have to use something else. I like Scilab, it works for everything I did with MATLAB except this. 

  

Scilab throughs and 'invalid handle' error when executing:

  dos('abaqus cae -nogui response.py','-echo');

at the line inside response.py:

  Job.submit(consistencyChecking=OFF)

 

It seems that Scilab opens a dos shell to execute abaqus but 'response.py' has this line inside it:

Static Riks results for load vs angles , load vs lateral deflection and load vs vertical deflection

Choose a channel featured in the header of iMechanica: 

I have differenet layups for cantilever beams. I run the static riks test from the eigen value in the first software ,giving values of initial arc increment of 0.005, mimumimum arc length increment as 1E-35 , maximum of 1000. The static riks gives good results for the notional loads for layup 30 -30 30 -30. However, keeping all other parameters same but for a different layup 30 -30 -30 30 ,the values from the staic riks are very very far from the experimental results.

How to define the sink temperature and film coefficient in Abaqus?

Choose a channel featured in the header of iMechanica: 

Hi, everyone. I am considering the heat conviction during compacting simulation by Abaqus. I was wondering that how to define the sink temperature and film coefficient? Is there any references for the two parameters of different materials?Thank you so much for your help in advance.Sincerely

Question about wire model with beam element in ABAQUS

I want to do a finite element analysis of the braid vessel stent model with the B31 beam element and the explicit solver, and I find that the wires in the analysis are discontinuous. Should I add some constraints or cross-sectional connections?

I set the radial displacement of all the nodes, as usual the stent should be extended, but the result was not, and the lines became independent segments.

NURBS patches (IGA) in LS-Dyna

Hi,

I am trying to use iso-geometric elements in LS-Dyna with the keyword *ELEMENT_NURBS_SHELL_PATCH. The job manager terminates without mentioning where the errors are.

Can someone help me with this? A sample .k file using the above keyword will be helpful.

Thank you!

Regards,

Harsha Reddy

How do I count Keyword Blocks in the Abaqus input file?

Choose a channel featured in the header of iMechanica: 

The Abaqus documentation, available here:

https://abaqus-docs.mit.edu/2017/English/SIMACAEMODRefMap/simamod-c-inpu...

states the following:

Certain keywords must be used in conjunction with other keywords; forexample, the *ELASTIC and *DENSITY keywords must be used in conjunction with the *MATERIAL keyword. These related keywords must be grouped in a block in the input file; unrelated keywords cannot be specified within this block.
