Surely it either is or isn’t, irrespective of what you call yourself. “As a centrist, I’m pretty sure the factual truth is somewhere between those two positions.” To paraphrase another of my recent favorites: (In this case, there’s the delicious added irony of an anarchist treating a belief system as an authority to conform to.) If you believe in prison abolition, you’d better have an actual reason, other than you’ve chosen an ideology that includes this view in its platform. “As an anarchist, I believe prisons as we know them should be totally abolished.” My favorite such statement goes something like this: We adopt a label for one reason or another - hopefully because it seems to fit views we already hold or develop authentic affinity for, but not always sometimes it’s even imposed - and then slowly, inadvertently, we let that label influence or determine our beliefs. This applies to adherents of just about any belief system, and almost all of us do it with one or another political, religious, or philosophical designation. If you use the label at all, it should come out something like: “I believe, which is part of what makes me an ist.” But for the most part, it’s best to stick to stating your beliefs, and leave the labels to conversation about the ideology itself. There are exceptions, but pretty much any time someone remarks, “As an ist, I believe …” they are getting it backward. …followed by a position the speaker holds. The code compiles when I use a Field with the full mesh size, but the simulation crashes (I think, the wrong values are picked from the field).You hear it all the time, even if you don’t notice. Solve(epsEqn) My problem now is, that the Field "epsilonOverwrite" needs to have the same size as the labelList keepCells (I think so). create labelList with cells to change for setValues functionĬonst volScalarField& fCheckTemp = tfCheck() Ĭonst labelUList& keepCells = setElements ĮpsEqn().setValues(keepCells, epsilonOverwrite_) fvm::laplacian(DepsilonEff(), epsilon_) I hope this was somehow more understandable :-). What I am now struggeling with is to built a labellist and a volScalarField with the cells forfilling an attribute (saying some scalar of the cell is smaller than some number), for which the setValues command should be used to replace the transport equations with the algebraic equations befor solving the matrix. To use the setValues I need to give the function a labellist and a volScalarField with the values to set for the cells. For this, I want to use the "setValue" command. I do not need to set the values at the wall, as they are already set by the boundary conditions, but the values of the cells which forfill the attribute to use the algebraic equations. So I need to set up the matrix with the standard transport equations and then replace some parts of the matrix with the algebraic equations. The problem is, that I need to include the algebraic into the matrix before solving it. I want to implement a two-layer turbulence model, so I need to use the transport equation for k and epsilon in the outer boundary layer, but closer to the wall I need to use algebraic equations to solve the turbulence parameters. Sorry, I thought it would maybe be too confusing :-). Creating labelList from cells with certain attribute - CFD Online Discussion Forums
