Hi,
I am also involved in implementing the similar problem. I also want to have clarification especially when implementing such relation to other problems.
Thanks

The minus sign is because the traction or force per unit area on the solid surfaces is the negative of the same quantity on the matching fluid surfaces.

I think the the stress (spf.T_stressx , spf.T_stressy and spf.T_stressz ) is acted on the fluid , while the force acted on the artery walls is -spf.T_stressx , -spf.T_stressy and -spf.T_stressz. They are a pair of acting force and reacting force.

in (r,z) coordinate system, these would be spf.T_stressr , spf.T_stressz right?

May this will help you , the minus sign would represent the force to "the fluid", if integral the force to the wall or boundary , "(spf.T_stressx , spf.T_stressy and spf.T_stressz )" would be the right choice.
