strictly bounded scalars
Hi all,
is anybody working with strictly bounded scalars in Version 1.6? if i put e.g. div(phi,U) Gauss limitedVanLeer -10 10 into the fvSchemes, when starting simpleFoam an error occurs with an unknown scheme and it shows me a list of available schemes where no limited schemes are listed.. i found this list regarding Version 1.5 interpolationScheme Valid schemes are : ( MUSCL01 localBlended Minmod limitedCubic01 QUICK MC limitedGamma upwind limitedLinear01 filteredLinear2 vanLeer limitedCubic SFCD midPoint clippedLinear outletStabilised SuperBee linearUpwind filteredLinear Gamma01 MUSCL limitedVanLeer limitedMUSCL Gamma limitedLimitedLinear vanAlbada downwind localMin localMax limitedLinear skewCorrected linear UMIST reverseLinear vanLeer01 limitedLimitedCubic weighted blended cubic harmonic OSPRE ) the entries: limitedGamma limitedCubic limitedVanLeer limitedMUSCL limitedLimitedLinear limitedLimitedCubic are not shown for me in 1.6.. anybody has experience with that? all the best, Moritz |
Hi Moritz,
you will not see the strictly bounded scalars because U is a vector field. You can check them for div(phi,k) or div(phi,omega). From my experience they work well, e.g. limitedGamma can give more stability for turbulence variables. Hope this helps. Best regards Ulrich |
Hi Ullrich,
thank alot for response, you saved my day as at least the solver is starting now:). I used div(phi,k) Gauss limitedGamma 0.5 1e-10 10 div(phi,epsilon) Gauss limitedGamma 0.5 1e-10 10 so i guess the 0.5 is for Gamma and 1e-10 10 i chose as the bounds for k and epsilon. By the way, what is the parameter for Gamma for? Unfortunately epsilon is still exploding after some iterations... any idea? all the best, Moritz |
Can anybody explain how strictly bounded limites works?
