I will give you the picture of my model. I will go with DPM modelling in the set up.

I need you to evaluate whether my model is right according to my assumptions.

I want to build a continuous moving fiber in a fluid of discrete particles.

For this I considered a rectangle, 'base' being the fiber. In boundary conditons, I have given moving wall conditions to the base thinking it will act as a moving fiber.

The other three boundaries are considered as left side being the pressure inlet, right side being the pressure outlet and top side being the outbound.

I just want to know whether I can give the left and right edges of the rectangle as pressure inlet and outlet or not.

I don't know any pressure details.

# in below picture

H1- top outbound (fluid which is far away from fiber)

V4- right end of the fluid medium

L5- radius of the carbon fiber( taken as axis-symmetric)

Please guide me how to proceed further...
