Conflicting BC on edge nodes

Hi all, Does anyone know, in the case of conflicting boundary conditions at the corner (in 2D) or edge (in 3D) nodes between boundaries, which condition takes priority? I am trying to prescribe a no penetration condition only, on the lateral walls of a valley glacier. However, the nodes which also b...

Re: Modelling ice tributary in 2D flowline case

Interestingly, Displacement 1 Load doesn't seem to do anything either. Is there something wrong with my NS Equation settings?

Re: Modelling ice tributary in 2D flowline case

Hi Peter,

Still no luck I'm afraid; am I maybe missing a keyword in the NS Solver section or something like that?

Cheers,

Joe

Re: Modelling ice tributary in 2D flowline case

Hi Peter, Thanks for your quick reply. I'm having some trouble implementing your proposed solution, unfortunately. Would you mind having a quick look over my SIF to see if you can spot any obvious mistakes? I've been trying to pinpoint the problem. I'm able to implement a nodal temperature load usin...

Modelling ice tributary in 2D flowline case

Hi, I've been working with Elmer this year to develop a 2D flowline model of a glacier in Greenland. I've hit a bit of a stumbling block with regards to modelling the additional mass input at the point where a tributary glacier joins the main channel. Is there a way to artificially create a 'mass so...
