Hi,

I have a pre-defined path and diameter of the runner of a mould(Please find the image below).I have created the runner as per the design but finally when I try to mesh it, message pop-up by saying "channel design system generation failed, runner/cooling diameter is too large".

Totally the design has 8 injection points I wanted to do it as symmetric analysis. by I'm not getting the symmetric wizard while meshing the model.

Injection pressure: 250bar

Runner diameter: 18, 14, 10, 1mm

Material: natural rubber

The weight of the part: 150g

Thanks in advance.
