Hi Millim, Maybe your potentials are mixed up? "PotA" should be "PotB" and vice verca. Just a comment: I would refer to the potentials as "PConduction" and "PStatic" or something similar. Then it is always easier to understand which potential you are dealing w...

Just a general comment on your rhetorics: I advise you to rephrase these type of comments a bit little more: 1. I am sorry Peter, just take one of your simple test examples where stat current solver is used 2. I think the only way solving that is the use of a "reset file", which is really ...

I am sorry Peter, just take one of your simple test examples where stat current solver is used, take a text editor and make global exchange of "Potential" by "XYZ" and you will see completely different results. That is because "Potential" is a regognized variable keywo...

Hi Peter, thanks for the answer. You say that one of the problem is meshing of the free space. At the moment this would not be a problem for me since I do not have mesh free domains in my model. But I guess that doesn't help since the time stepping would be an issue. One would have to calculate seve...

I think I found the problem: I have too many radiating surface elements. There are in total 97473 elements. check this out: This is what I write in the ViewFactors.f90 ! CALL ViewFactors3D( & ! N, Surfaces, TYPE, Coords, Normals, & ! 0, Surfaces, TYPE, Coords, Normals, & ! Factors, AreaE...

Hello, I am tracing a bug in ViewFactors.c: I have the following debug code in the "static void IntegrateFromGeometry" fprintf( stdout, "Debug: ViewFactorCompute: "); fflush( stdout ); (*ViewFactorCompute[Elements[i].GeometryType])( &Elements[i],&Elements[j],0,0 ); fprint...

Hi Eelis Now there is no feature like you request currently. In ElmerGrid there is some primitive feature (-boundbound and -bulkbound) that try to define new boundary elements from unions of existing ones. This hasn't been too much used and may fail for some elementtypes. So you can create a union ...

Hi Peter, thanks for the exhaustive answer. So you are saying that in elmer the intersection of two geometry groups (with respect to the elements) is always empty due to the tag limit? And how about the "mesh.elements" structure, does that support "multiple groups" for elements. ...

Hello, I'm thinking about boundary condition definitions and actually this applies for geometry groups in general: Let us assume I have a model boundary Omega = Union(Omega_1, Omega_2), Now, normally we'd prefere Intersection(Omega_1, Omega_2) = Emptyset, And this is how in Elmer it usually is (if n...

Hey Everybody, 1.Is it correct to assume if what I want to detect are large deformations I should use non linear analysis? 2.Can I use a transitive solver with ElasticSolve so I can look at intermediate stretches (ie below the full 1.5x stretch)? 2.Will someone help me with the .sif file? Hi Alok, ...
