Hi,

the common way is to convert your surfaces to STL and then import them
into Yade. GID is not supported by Yade due to its commercial nature.

Cheerrs,

Dear Yade users and developers,

After almost 8 months of development I am glad to announce
the next Yade version 2016.06a. The complete changelog
you will find as always at the end of this message.

The versioning of releases is changed and now is in the
form .MMx. Where x is the letter, which can be
changed by minor updates in the stable releases.

Thanks all for contributions!

Jan Stránský proposed the following answer:
Hi Jabrane,
you should put "this->dAX = dAX" to a place such that dAX is not changed
afterwards. e.g. it is changed at
https://github.com/yade/trunk/blob/master/pkg/dem/UniaxialStrainer.cpp#L106
So after line 121 (in the original file) it should be the correct position

Hello Jan,

The behavior of dAX is related to the line in which i put "this->dAX = dAX"
In fact i put  "this->dAX = dAX" just after 
https://github.com/yade/trunk/blob/master/pkg/dem/UniaxialStrainer.cpp#L95
and just after 
https://github.com/yade/trunk/blob/master/pkg/dem/UniaxialStrainer.cpp#L122 and 
i get different value of dAX.

The question is where do I put  "this->dAX = dAX" to get the real
behavior?

Best regards.
Jabrane.

Hi Jabrane,

But i have a question how do you know that dAX is a local variable ?


it just comes from how C++ works / is defined, nothing else.

"Real dAX" in cpp file inside a function simply declares a local variable.
No matter if the class has a member with the same name.

Question #295301 on Yade changed:
https://answers.launchpad.net/yade/+question/295301

Jan Stránský proposed the following answer:
Hi Jabrane,

you came to c++ variables and scopes [2].

to get correct behavior, one option is to change the declaration of dAX
[1]. Currently (Real dAX=) it creates a new variable, unrelated to
strainer.dAX.
Just delete Real (i.e. assign directly dAX=...) and then dAX refers to the
class member strainer.dAX.

Another option is leave it as it is and add
this->dAX = dAX;
somewhere after dAX is computed.

cheers

Status: Open => Answered

Jérôme Duriez proposed the following answer:
Hello,

You tried to modify the source code, that's it ? Did you also modify
UniaxialStrainer.cpp in order to update this new variable "dAX" ?

As a side note, did you consider to use TriaxialStressController ? In spite of 
its name, it should be possible to use it for uniaxial loadings. And 
TriaxialStressController provides already access to external work:

[Yade-users] [Question #295301]: calculate external work in Uniaxial Strainer

2016-06-14 Thread Yor1

New question #295301 on Yade:
https://answers.launchpad.net/yade/+question/295301

Hello Yade users !

I try to calculate the external work on a sample in tensile test.
In fact, i calculate the external work with this simple formulate
"Wext_incremental=AppliedForce*displacement_incremental".
I want to integrate this formulate in the sources UniaxialStrainer.cpp
In uniaxialStrainer.cpp the incremental displacement is calculated and named 
"dAX".
In order to verify the behavior of incremental displacement, i define "dAX" in 
uniaxialStrainer.hpp like this
((Real,dAX,0,,"Current incremental displacement")) in the line 43 of 
UniaxialStrainer.hpp

My problem is that in the simulation of tensile test , dAX=0 during the 
simulation.
I call dAX in the python script strainer.dAX
I don't understand where is the problem.

https://github.com/yade/trunk/blob/master/pkg/dem/UniaxialStrainer.hpp
https://github.com/yade/trunk/blob/master/pkg/dem/UniaxialStrainer.cpp

Best regards.
Jabrane.
