"autodesk moldflow design link" to improve element matching with inserts

[pbäuerlein]

Hi,

i want to analyse a insert molding.

To improve the match between part and insert i am using the same contact surface.

But it is very difficult to deal with that when using complex geometries.

I read something about "AMDL"(autodesk moldflow design link) which matches the mesh of the contact surface between the parts.

What is this product about ? I don t find anything at all in the internet.

When modeling part inserts, the mesh of the insert must match the mesh of the part.

1.Check the surface mesh on the insert and compare it to the part.

2.Fix the insert mesh.

3.Mesh the fixed insert and connector with tetrahedral elements.

4.Add the two meshes together.

5.Assign the part insert properties.

6.Run the analysis.

7.Review the results.

Let me elaborate!

First, you create the mesh of the insert and the part mesh separately and then call them into a single file. The problem in this is that the mesh interface of the part and insert will be inappropriate resulting in element intersection. The solver also requires for time.

Second, prepare the part mesh. Copy/duplicate the study file and create a separate file. In this new file one has to create the insert mesh from the part mesh itself. This methodology is mostly suggested and the best part is that there is no mismatch in the insert and part mesh interface. Element intersections would be 0 though overlapping cannot be avoided which is very logical for insert cases. Overlappings are not an issue in case of insert overmolding.

Thanks for the quick response.

I know this method is the best way for good results.

I already have simulated my parts with this.

My question is if there isn t a more comfortable way of getting good results with part inserts.

For example meshing the two parts at the same time when imported from CATIA so you get the same surface immediately.

Therefore i asked for the programm AMDL which can be used for the CAD - programms.

Hi,

with Autodesk Moldflow Design Link you can mesh assembly contact faces.
It can also be used for direct import of cad bodies to Synergy, to mesh assembly with contact faces in Synergy.

Autodesk Moldflow Design Link is available in 3 "flavours":
Autodesk Moldflow Design Link for Pro/Engineer : .prt, .asm, step, iges
Autodesk Moldflow Design Link for Parasolids: parasolids, step, iges, sldprt, sldasm 
Autodesk Moldflow Design Link for CatiaV5: *.catpart, *.catproduct

Autodesk Moldflow Design Link 2011 supports up to CatiaV5 R19.

You can find a reseller in your region at:

Hope this helps.

Regards,

Berndt
