Regarding mold flow simulation
(OP)
Dear all,
This is regarding plastic flow simulation using mold flow software.
We have a problem while running analysis with mold inserts,
We tried following two approachs
Approach 1
We meshed mold insert and the plastic part togeher as a single integral part in Meshing software (Hypermesh). Then in MF, we selected appropriate insert surface elements in fusion mesh as mold insert and assigned properties for it .when we fired the analysis in molflow, free edges were indicated after completion of flow,cool analysis and the warpage analysis was failed.The error indicated was free edges along the interface region between insert and plastic area.
Approach 2
In second iteration, By using fusion mesh option,we meshed the plastic volume and meshed seperately the insert volume.now when i check for free edges, Mold flow clearly indicates there are 400 free edges and overlap which is exactly at the interface area.i want to run the full analysis including warp.now the mesh has a good connectivity between both the plastic area and insert area.
We are clueless and look forward for suitable directions to proceed further.

RE: Regarding mold flow simulation
What is the insert?
If it is not plastic why do you have it in mold flow?
I think i would used a model that only represented the plastic peice of the total part.
Not sure what you are hoping to get from the "connectivity" between the peices.
I would set my cooling etc up with the mold properties and temps and the treat the insert region as a different type of steel BeCu etc and observe cooling/warp variations that way.
I could be off cause i dont know exact what your doing but just thinking out loud hope it helps.

Pl. do google search..You will get relevant details.
Also pl. refer this link,

We already resolved the insert modelling problem and we will share the details in next thread.
