The double dot product operator seems to calculate the incorrect result for when one argument is of class "symmTensor" and the other class "tensor"
I have attached two examples: checkTensor - calculates several operation with symmTensor and tensor's dnsFoamCheckTensor - modification of dnsFoam which calculates S:S, S:D using S of class symmTensor and S of class tensor. Below is some output of dnsFoamCheckTensor S:S  S:D  S2:S2  S2:D  D = grad(U) S = symm(D) S2 = 0.5 (D + D^T)  checkTensors.tgz dnsFoamCheckTensor.tgz Dave |

Yes you are quite right there

Yes you are quite right there is a bug in the && operators between symmetric and non-symmetric tensors, here is the fix
TensorI.H to replace the TensorI.H in OpenFOAM/OpenFOAM-1.4.1/src/OpenFOAM/primitives/Tensor |
