[petsc-users] Extending PETSC-SNES-VI to linear inequality constraints,

[subramanya sadasiva]

Hi, Is it possible to extend PETSC-SNES VI to handlie linear inequality 
constraints. My problem has  4 variables . 2 of them have bounds constraints, 
as well as a linear inequality. At present I've implemented an augmented 
lagrangian method to handle the linear inequality and I let SNES VI handle the 
bounds constraints. However, the convergence of this method is very poor. I'd 
like to know if there was an easy way to get SNES VI to handle the linear 
inequalities as well. Thanks, 
Subramanya
