Hello,
I tried to set exact position for an injection coin. (Simulation Moldflow Insight 2013 SP1)
The Simulation Moldflow Wiki says:
"Use the Injection Location Properties dialog to set the coordinates for your injection point(s).
However "properties" in the rc-menu is greyed out.
What am I doing wrong?It's funny how this trivial question, originally posted in this forum back in 2012 and asked over and over again by new Insight adepts, has still not been answered - even though exactly the same explanation about injection location precise X,Y,Z coordinates is still present in Release 2019 Help system:
http://help.autodesk.com/view/MFIA/2019/ENU/?guid=GUID-7CF36029-E475-4542-B610-C9A6A3695A4C
People - especially those who have seen how obvious it is in Moldflow Adviser - only seem to get some understanding of why locating the B.C. "injection cone" symbol is not THAT relevant after they learn more about meshing the model, whereas nodes can indeed be created by X,Y,Z coordinates and only then, the injection cone location can be applied to such a precisely defined node. However as we know, the recent trend is applying more and more B.C.'es (Boundary Conditions, including Injection Location among many others) directly to the CAD geometry - i.e. even before the mesh is even created! This is why this seemingly trivial question ("how do I place the Injection Location cone precisely at given X,Y,Z coordinates) started showing up again and much more often than before...
This is why I'm bumping up this old thread - and asking: dear Autodesk, are we missing something or is the explanation in the Insight 2019 help system which I posted a link to simply wrong?
Thanks,
Piotr
Hi @Anonymous, hi @Anonymous
Thanks for posting in this forum!
Yeah, this is a controversial topic. What we need to understand is that if the Injection Cone (IC) is not on the exact coordinate, it will be not further away that the equivalent of the edge length, which in most of the cases is good enough.
If the precise location of the IC is so important, there are two different approaches:
Despite this workaround, I will also recommend you to post this idea of direct location of an IC as an enhancement in our Moldflow Ideas.
I hope it helps!
Cheers,
Javier

Thanks Javier,
As we know there is quite a number of work-arounds for this "issue" so I guess the most questionable and unfortunate is not how we do it, but the mere fact that the newcomers to Moldflow Insight (including previous users of Adviser where the injection location is an object which can be placed and manipulated using precise X,Y,Z coodrinates - it takes some time during my Insight courses that in Insight, the IC (injection cone) is just another BC and it so happens it doesn't have Properties associated to it which could be directly edited... One of my favorite work-around I've been using for many years (and it seems I'm not the only one - Stefan Kuehne just wrote me and e-mail with exactly the same method proposal) is - before even generating the mesh - to create a "Node by coordinates" (with its X,Y and Z being exactly those desired by the user for locating the IC), followed by creating the IC BC anywhere in the model; it's than enough to perform a "Merge Nodes" operation with the first node as the target, and the node the IC is attached to - as the one to merge... Job done!
Thanks and Regards

Hi Piort,
I totally agree with your observations.
Just let me add some ideas. Injection Cones are always BC, also in Adviser. The advantage in Adviser is that the mesh (and nodes) are transparent, and therefore you can move IC based on its coordinates. In Insight, the IC are always attached to a node, and it is the node the one who have the coordinate properties.
Thanks for helping new users with your valuable posting!!
Cheers,
Javier
