Automatic beam element between part and injection location

[Anonymous]

Problem:

When the feed system of a part is not modeled and the gate location is placed directly on the part, the thermal conditions and the conditions of the flow front are not always quite clear. That's why at user meetings it has been recommended to always place at least one beam element between gate and part. In the beam element the boundary conditions for the flow are clear and the diameter of the part-beam connection is defined (which is not always obvious when placing a gate with specified diameter on a 3D-Mesh depending on mesh coarseness). 

Solution proposed:

Automatic insertion of a beam element on a selected node when setting an injection location directly on the part. The beam element has preferably to be perpendicular to the part surface (if flat) or with definable orientation (if not flat).

Thanks for consideration.

Hi PA_Trickk.

Good Idea.

Also the shear rate on gate will be more of reality.

Because if you set only a gate location directly on part, the shear will be to low.

Hi PA_Trickk,

There is no difficulty in doing this. But how would you define diameter?

Do you expect to define diameter on the injection location?

Hi XUSHO

the gating diameter was already define in the advanced options (solver parameters for thermoplastics injection molding). can you use this (gate contact diameter) to create a "gate beam"?

I also would appreciate this.

Hello XUSHO

Good to hear that. It would be a nice time saving and practical feature. Since you recommend not placing the injection cone directly on the part it seems a Logical consequence to me that this should be implemented in order to improve result quality. As Lothar said (thank you) the "gate contact diameter" out of the advanced settings should be the defining diameter for the beam.

"gate contact diameter" is not specific to a particular gate. And the default value, 2mm, may not be good for all models. So the mesher does not use that parameter.
