Hi,
I'd like to calculate the stress applied on a beam due to the temperature increasing. The beam is 1m long and diametere is 0.1m. The displacement is neglacted all over the surface of the beam. The problem seems simple, but solver doesn't find a solution. Any suggestion? Attached are the input files (except for the mesh). |

Does anyone say me if there is something wrong in the fvSolution file?
Code:
solvers { "(D|T)" { solver GAMG; tolerance 1e-06; relTol 0.9; smoother GaussSeidel; cacheAgglomeration true; nCellsInCoarsestLevel 20; agglomerator faceAreaPair; mergeLevels 1; } } stressAnalysis { compactNormalStress no; thermalStress yes; nCorrectors 100000; D 1e-06; T 1e-06; } Code:
d2dt2Schemes { default steadyState; } ddtSchemes { default Euler; } gradSchemes { default leastSquares; grad(D) leastSquares; grad(T) leastSquares; } divSchemes { default none; div(sigmaD) Gauss linear; } laplacianSchemes { default none; laplacian(DD,D) Gauss linear corrected; laplacian(DT,T) Gauss linear corrected; } interpolationSchemes { default linear; } snGradSchemes { default none; } fluxRequired { default no; D yes; T no; } |
