Hello,

 

Are you using coupled scheme for P-V coupling? 

This is what the user's guide says for Porous Jump BC: "If convergence instability is observed using the coupled pressure-based solver, it is recommended that you change the pressure-velocity coupling to one of the segregated schemes."

 

For more information, refer to this section of the user's guide: 7.4. Boundary Conditions (ansys.com)

Thank you!
