Hi all,

i am playing a bit with LTSInterFoam. The idea is to simulate the steady state movement of a meniscus in different capillary tubes and compare the solution with the unsteady one.
As a starting point i had a look at wigleyHull tutorial in which everything seems to work fine.
Then i took the capillary rise tutorial of interFoam and i tried to get a steady state solution with LTSinterfoam, using the same BC. I played with many different combination of schemes and solvers with no success: or the solution diverges (alpha explodes, continuity errors explode) or the solution is physically not correct. When the meniscus reaches the equilibrium configuration i think a steady state solution should exist, so where i am doing wrong?
Are there any limitations using this solver?
Is the presence of capillary pressure that might generate problems (in wigleyHull tut, sigma is set to zero)?

thanks

andrea
