Re: ListGetInteger error in Periodic BC

Hi

Note that the index of "Periodic BC" refers to the i in the "Boundary Condition i" declaration. Only if your "Target Boundaries = i" for all i, are these the same. Often there are less BCs than there are Target Boundaries.

Re: Pointwise and Elmergrid

Hi Markus

In what all formats can Pointwise export the mesh?

Problem with many commerical software is that they do not even like to support possible co-operation with OS tools and this is reflected in the possible output formats.

Re: ERROR:: ElementMetric: Degenerate 3D element

Hi Matthias Do you have a small case on this. Generally it would suggest that there is an element where two nodes are at the same coordinates, or too close to form any proper element. This could be a property of the initial mesh, or if there are deformations it could results later. I would think tha...

Elmer FEM Course - from PCs to supercomputers

Hi All We're happy to announce Elmer course in the PRACE Advanced Training Center program. http://events.prace-ri.eu/conferenceDisplay.py?confId=29 This will include a rather standard two-day Elmer course followed by a workshop type of session on recent and umcoming parallel developments. A detailed...

Re: Elmer p-adaptivity

Hi Some critical lines of the p-core are: n = GetElementNOFNodes() nd = GetElementNOFDOFs() So the number of nodes and the number of dofs are not the same. This will be reflected in many places of the code. You should not have to do any low level modifications. Just take use of the higher level subr...

Re: Simulation of Sonic Crystals

Hi I tweaked the code for the current version so that you test whether density is given: ! Initially density was not used in the Helmholtz equation. However, if there ! are several different densities it must be used and hence it was added later. ! For backward compatibility also the version where d...

Re: basic question

Hi, I guess you mean by q(n) the normal flux that is left as a result of the weak form. This is implicitely included in the matrix equation and hence need not to be formed on the r.h.s. -Peter

Re: How to get the solution of a point diffeent from node

Hi

A variable, say Var, is usually associated with a permutation vector. So whereas you get, say X-coordinates of an element with

Code: Select all

Mesh % Nodes % x(Element % NodeIndexes)
You get the corresponding field values with

Code: Select all

Var % Values( Var % Perm( Element % NodeIndexes ) )

Re: DEM to mesh

Hi You can also do the meshing totally separately from the DEF. Then you can read in the elevation with GridDataMapper, for example, and morpf the mesh with StructuredMeshMapper (extruded mesh in depth direction) or MeshUpdate (arbitraty meshes). Haven't tested the workflow but it should be pretty m...
