generally the recommendation is:

- model 1 cavity, and duplicate cavities in Moldflow Adviser.

- the runner system should be modeled in Moldflow Adviser, so they are beam elements


If you model runners in cad, are they 3D?

And do you run a 3D analysis in Moldflow Adviser?


Otherwise, if running as Dual Domain the runners are meshed with triangles, which is not recommended.

This can create unexpected result.


Hope this helps.
