Hello everyone,

I am trying to design a plastic part and its mold. I am having trouble meshing/designing the runner.

When I use Shell mesh, I can choose the cross section of runners and gates from circle/half-circular/rectangular/trapezoidal etc. However, when I use Solid mesh, I can only select a circular cross section (I want to select a half-circular runner). I need to use a solid mesh for cooling channel and mold design. What should I do?

Also, when I use Solid mesh to create runners, I get an error message "Runner length is too short. Mesh generation failed". I altered the runner sketch several times but I wasn't able to mesh the part (Runners, Cooling Channels and Mold) using Solid mesh.

I have attached the multi-cavity part file.

Can anybody please help me out?

Thanks
