May the existing N-S FlowSolver handle 1D issues?

Post by nickwan »

Dear all,

I am trying to use the N-S FlowSolver for solving 1D issues. The case is that wind blows an open ocean. I want to see how the turbulent diffusivity and velocity vary vertically with winds. Ignore horizontal variations, instead, focus on the profiles of the turbulent diffusivity and velocity. A 1D space was meshed with 204-type bulk elements and 101-type boundary elements. My test has never succeeded after many tries.

Does it mean the existing N-S FlowSolver may handle 1D issues by design?

All the best

Nick

Hi

Whereas many solvers of Elmer are independent of the dimension some are not applicable to 1D cases. The Navier-Stokes equation only works in 2D and 3D cases. There are some reasons for this. For one, the continuity equation gets eliminated when there is just one dimension. Perhaps you could write out the equation that you want to solve.
