Elmer Discussion Forum

Could you please specify how you learned to work with Elmer? How do you solve an issue? Well, I coded large parts of the code. If I have an issue I code some more ;-) This is a small open source project and this support is pro bono. Commercial codes are there for a purpose as they can have an army ...

DefaultSolve() is usally the routine that solves for the linear system + does some relexation + checks for convergence. The modules usually just do the physics specific stuff i.e. discretize the PDEs into linear systems. -Peter

Hi Have you read the chapter for HeatSolver in Elmer Models Manual? I know the documentation is limited but >700 pages still something. It just reflects the width of the application fields. Heat transfer is just one of many. There are no units specified since the user can choose whatever consistent ...

Hi All, I've been working a little with this turbulence stuff the last two days. Some baby steps taken. So far I'm taking some ideas from: http://num.math.uni-goettingen.de/bail/documents/proceedings/mierka.pdf The work happens on branch "KESolverRevisit". What I've been trying to do is to gradually...

Sure, for example -Peter

Hi

This routine just picks the local displacements related to an element from the global solution vector. So there is no solution step required.

Hi Kevin,

Yes, I realized there was a bug introduced. Quick tests were passed but many others were not.

The current devel version hopefully works better. Last commit was just minutes ago.

Thanx for testing & reporting!

Hi

If you know the pressure of the fluid domains there is no need to mesh them. Just apply "Normal Force" (same unit as for pressure) on the fluid walls.

Hi

It is indeed better to start with "idealized". That should usually work easily. However, that will give you no heat exchange between bodies.

You don't seem to have the ViewFactors binary in your path.

Hi

The difference is that in PDEs the "bofy force" is typically a source term integrated over volume and the "boundary condition" often comes from the weak formulation and is integrated over the boundary area.

When using nodal loads an discrete level these are more alike.
