Hi
The interpolation should be performed over a relatively small part of the domain not all of the mesh. Should I still use "InterpolateMeshToMesh"?
Thanks,

Some required mesh routines
Hi there I want to accomplish the following tasks: 1- Identifying the element that contains a particular coordinates point 2- Distribute (interpolate) a quantity (e.g. velocity or force) from a node to its surrounding nodes in a particular domain Is there any routine available in Elmer to perform th...

Overlapping meshes
Hi there I want to solve an FSI problem that involves two overlapping meshes, data of which must be interpolated conversely (from one to another and vice versa). One is background and fixed and the other is moving. Do you have any idea for solving such kinds of problem in Elmer? Thanks, Diana Carlso...

Problem with ALE formulation of Navier-Stokes
Hi there I still have problems with ALE formulation used for solving flow equations in Elmer. Let me explain via an example, (i.e. Tutorial 16: Fluid flow around an elastic beam). The problem is steady-state so the ‘compute mesh velocity’ option is not active and the mesh velocity is zero. So in ‘Na...

fluctuating pressure levels
Hi there I’ll be grateful if somebody gives me some information about the following part of FlowSolve subroutine. A book, paper or any other theoretical reference will be ideal for me. Furthermore, what is LocalNodes? !------------------------------------------------------------------------------ ! ...

Re: Perm
So you mean that by setting "Optimize Bandwidth=False" we will have
TempPerm( NodeIndexes ) = NodeIndexes . Am I right?
Thanks, Diana
TempPerm( NodeIndexes ) = NodeIndexes . Am I right?

Re: Perm
So if for example, for our linear quadrilateral element we assume NodeIndexes=[11,7,4,8], which one would be right? a or b (just qualitatively)? a) TempPerm( NodeIndexes ) = [4, 7, 11, 8] TempPerm(Indexes(1:nd)) = [4, 7, 11, 8] For i =1 --> TempPerm(NodeIndexes(i)) = 4 ALL( TempPerm(NodeIndexes) > 0...

Perm
Hi there I’ll be grateful if somebody gives me some information about the perm variable possibly via an example. I’ve read some about it in Elmer’s documentations but e.g. I can’t understand the following expressions for a quadrilateral element: TempPerm(Indexes(1:nd)) TempPerm( NodeIndexes ) k = Te...

DefaultUpdateEquations
Hi there
What is the difference and use of DefaultUpdateEquationsC and DefaultUpdateEquationsR? I know that The local matrix is added to the global coefficient matrix of Elmer Solver calling the subroutine DefaultUpdateEquations.
Thanks,

NodalBasisFunctions1D
Hi there I’m studying the ElementDefinitions module and I have problems interpreting the following formula from the subroutines NodalBasisFunctions1D: s = s + coeff(i) * u ** p(i) Especially I can’t understand the meaning of coeff(i) and p(i). Furthermore, I don’t know if ‘u’ is the point’s coordina...
