haibinli is on a distinguished road
I want to calculate the formula below:
T=C.E
where T={txx,tyy,tzz,tyz,tzx,txy)
E={exx,eyy,ezz,eyz,ezx,exy)
C is Huke coefficient and C={
c11,c12,c13,0, 0, 0,
c12,c22,c23,0, 0, 0,
c13,c23,c33,0, 0, 0,
0, 0, 0, c44,0, 0,
0, 0, 0, 0, c55,0,
0, 0, 0, 0, 0, c66}

How should I declare T,E and C in OpenFOAM,
Is there anyone who can help me please?
THANKS VERY MUCH!
