I am new to ANSYS and currently working on single screw extrusion simulation. The streamline is only appear at the inlet but it does not complete the path until outlet.

I have tried to increase the mass flow rate, temperature imposed, larger number of iteration, or changing it to slip condition... but none of it is helping...

May I know what could be the possible mistake? I am very appreciate for your help.

Maybe you have selected a single plane in your setting for streamline in CFD Post processor.
Try inserting vectors from inlet to outlet to see if that solves the issue.

Hi, Burhan.
I used 3D streamline and make it start from inlet.
I tried to insert vector, it also only appear at the inlet.

Thanks all, problem solved. I guess is my screw clearance is too small so the plastic can't flow and only appear at inlet.
