I want to simulate a overmolding-process, with an insert out of metal. I've changed the insert-mesh property type to "Insert Part". But when the simulation runs, it filles the insert volume. What am I doing wrong?
Thanks for help :-)
Sorry, i forget to say, just the part of the insert volume, which is inside the "polymer"-volume gets filled, not the volume outside. I tink the problem ist the there are two meshes overlayed.
I've made a picture to show you what i mean.
Hope you can help me.
It seems that your mesh is bad.
Take your CAD model, subtract insert (white) from polymer (green).
Then mesh both of them, ensuring right contact between them.
In the end You shouldn´t have any intersecting elements.
Hope that I described it quite clear :-)
I've deleted the parts of the polymer-model, wish had been "mixed" with the inlay, in my CAD tool. Then I meshed both seperate and changed the inlay properties. Is that what you mean? It would be nice, if Moldflow would see that it should not mix the meshes at complex parts.
If You meshed them separetly, then You need to ensure perfect contact between the insert and the part.
If You will mesh them together, You can use option `Precise match` - and MF will do it for You.
@ucornes: it depends with what kind of models You are dealing with.
I notice that with a small and simple parts, 'precise match' is working pretty fine.
Big parts with a complicated geometry (in the contact area) and we can expect that it will not work or You will need to correct a huge amount of elements.
The question is also with which MF version You are working with. My personal feeling is, that between MF11 and MF13 they made some improvements in this field. How is it working in MF14 - I have no idea (yet).
Well, I actually work on MF14. I design plastic parts for small appliances, which have really complex surfaces and what I have seen is that I will have to continue copying and pasting and stitching meshes...
