fvTensorMatrix equation solving ?
 

HI,
i have a tensorial equation to be solved for the tensor Y:

fvTensorMatrix YEqn

when i run the solver i see that:
smoothSolver: Solving for Yxx, Initial residual = 0.875064, Final residual = 1.60516e+149, No Iterations 1000
smoothSolver: Solving for Yxy, Initial residual = 0.686555, Final residual = 8.05809e+148, No Iterations 1000
smoothSolver: Solving for Yyx, Initial residual = 0.686555, Final residual = 8.05809e+148, No Iterations 1000
smoothSolver: Solving for Yyy, Initial residual = 0.872595, Final residual = 1.59013e+149, No Iterations 1000
smoothSolver: Solving for Yzz, Initial residual = 0.873874, Final residual = 1.60776e+149, No Iterations 1000

my question is, why Yyx is solved however it is symmetrical, and Yxz is never solved?

however In my defintion for Y, i defined it as a total general matrix volTensorField Y.
Is it the problem in the fvTensorMatrix Equation ? can it solves a tensorial equation for a general tensor Y? or only for symmetrical defined tensors?
any ideas ?

thanks,

Looks like your mesh is 2-D or the missing components are uniform.

hi thanks a lot prof. hjasak, i solved the problem, it was inside the choice of the solvers' settings in addition to the relaxation-factors.

thanks a lot

hope to meet soon at the 6th OpenFOAM Workshop in PENNSTATE
sincerely yours,
T.D.
