I don't know this command.
Where do I find him?
Are you sure that's your name?

vai with analysis - molded part validation

 

[matfio]

I had heard that they had inserted the Moldovaflow (easy fill) from version 8.5 and from the bundle mach3 but to me it does not work

I understand now what you're talking about, but it's not called easy fill.http://www.youtube.com/watch?v=ss6atf3xfk4&feature=g-user-u

I must pass by:
-analysis
-molded part validation
-easy fill
and then I find run flow analysis (as in the video posted by you)

unless you insert the fast icon as in the video

My question is, does it take a separate license or how did I hear it work for those who have mach 3? the error that gives me is "no flow analysis application is found"

the problem must be reported to gtac.
However, you need to download from the ftp area of siemens plm Moldovawizard.zip and disappear it in its folder.
the necessary license is that of Moldovawizard.

symptom/problem
---------------
accessing analysis --> molded part validation --> easy fill got error:

no flow analysis application is found

solution/workaround
-------------------
you need to go to http://ftp.ugs.com/
product updates --> nx/unigraphics --> moldwizard folder --> nx85 --> download
easyfillnx8.5_data.zip and follow instructions from easyfillnx8.5_data.txt to
install it.
if you are using mold wizard , you don't need to install this since it is
included in the data zip file.

ti suggerisco anche di segnalare il fatto che se hai una versione di vc 2010 (microsoft visual c++ 2010 redistributable package) più aggiornata, lui continua a proporti di installarla ma chiaramente non ci riesce perché microsoft non permette un downgrade e quindi non ti funziona.

excuse the question maybe they are out of thread however to avoid starting another discussion and since we talk about Moldovaflow placed here mine.

Moldovaflow is reliable as results?

that is:
If you tell me that plastic has a return a twist a swelling the dats that spit out are reliable if and what is its error toll?

is not Moldovaflow of autodesk, but of Moldovaex.
data is reliable if the data entered is correct (material and stamping data).
being an analysis to the finite elements, as happens with the fem, everything depends on the inserted information.

 

[flaviobrio88]

thanks for the answers:

if the data say that the printed e.g. swollen in an area and that even moving the inject points does not solve the problem happens that you discard the mold by compensating the inflating in an opposite way?

the plastic doesn't inflate, at most it retreats.
If you inflated, it means someone or something injected a gas inside the mold.
plastic injects into the liquid state and returns to the solid state, which is why I say it withdraws.
I wouldn't want you to ask for lumens on your issues that you didn't specify.
I can't give you an answer with so little data.

 

[flaviobrio88]

is inflated in the sense that retreating "engaging" in the central area
in any case when withdrawing the withdrawal is always constant?
So enough gives a scaled movement?

No, he doesn't always pick up constantly.
the withdrawal is influenced by many things:
- non constant product thicknesses.
- mold cooling circuits.
- injection points chosen.

on one side, give in (simple) scaled movement, not always is enough.
On the other hand, even blindly trust a Moldovaflow simulation (also with correctly inserted data) to "vitize" the mold, is not always correct, as any withdrawal abnormalities, are not always simulated correctly.

the best thing is always to make the thickness (as much as possible) constant, and the cooling (as much as possible) homogeneous.

thanks beppino,
I needed this information, because in automotive the calculation fem oscillates 0.3 to 0.5 error, however on a large mold.

In this case the values are not taken into account but only serves to see about how the print behaves and therefore it corrects manually without being to compensate according to the valleys of the simulator, correct?

in technical jargon the deformation is called risucchio .

in thermoplastic molding besides this there are also plastic deformations precisely that they suffer from geometry and can hardly be foreseen.
In some cases it is necessary to intervene in the back with "victims" but to obtain satisfactory results the stamping cycle must be extremely controlled and constant.
sometimes even a different batch of material can create differences between printed; I am talking about pieces but with dimensional tolerances extremely contained in the order of a few cents of millimeter

 

[flaviobrio88]

Each field has its own caxxis, for example, in the sheet, the result is changed even in the "sheet" section, so if a sheet of sheet turns it on the other side can come out a different result.

to calculate the elasic return there are simulators that tell you in mm what deformations undergoes the sheet and who makes molds use this data to compensate for the return.
what I understand and that in plastic this does not happen despite the problems are similar, but they take the data only to have an idea how plastic behaves, right?

 

[IPdesign]

exact, as I say, the results of the Moldovan simulation must be taken with the benefit of inventory:-d .
in the sense that grossly help you but in detail you never know what happens

 

[Utente NX]

without analysis, you'd crave in the dark, with a good analysis, you have results that would avoid gross and even medium-low errors.
personal experience.

Having a program that allows me to take fem data and from these pull out a model in surfaces with opposite values, I wanted to know if it was the case to present this solution to plastic molders, but (as I suspect) plastic simulators are not ready for this.

hi flaviobrio88, I press that I do not know nx but only Moldovaflow because I use it daily for filling/cooling and deformation simulations. Unfortunately the moldists are a somewhat 'particular' category and these analysis tools are not seen (often) well.
Moldovaflow analysis, to be done well, should be performed in the initial phase of design of the piece. the Italian tendency, however, is to make it at the end, in finished mold and with the pieces in hand.
Over the years I have been able to compare the results of Moldovaflow with real models (printed). the fact that returns Moldovaflow must be interpreted and filtered by the analyst otherwise you may be mistaken.
as you see the story is not simple it is not to crush 2 keys and wait:smile:

changing topic, I saw that nx introduced Moldovaex. I have customers who have Moldovaex and require me analysis in Moldovaflow because the sw is unable to return a certain result. Moldovaex is very limited compared to Moldovaflow. can go well for a quick read of filling or to see macroscopic errors.

bye:

is true what you say about the differences between Moldovaflow and Moldovaex, but it is also true that Moldovaflow costs from 10000 to 20000 euro, while Moldovaex3d base, almost give it to you in comparison, you just need to integrate it into your cad.
so, rather than nothing is better rather than.
