I noticed that expression a) works while b) and c) does not. I use V 1.3

volTensorField T = ...;

a) Foam::inv(T);

b) Foam::cof(T);
error: 'cof' was not declared in this scope.

c) Foam::cofactors(T);
error: no matching function for call to 'cofactors(Foam::volTensorField&)'

Thanks.

Currently (version 1.5) the "cofactors" function is defined for:

SymmTensorI.H://- Return the cofactor tensor of a symmetric tensor
SymmTensorI.H:inline SymmTensor<cmpt> cofactors(const SymmTensor<cmpt>& st)
TensorI.H://- Return the cofactor tensor of a tensor
TensorI.H:inline Tensor<cmpt> cofactors(const Tensor<cmpt>& t)

if you think it would be useful to have this function available at the field level I will propagate it through.

I managed to get cofactors with an indirect way by:

volTensorField M ...;

Mcof=(inv(M)*det(M)).T();

but it is not efficient. I would be grateful if you could propagate such cof function to the field level (similar to inv) in both definitions. If you could post the modification relative to V1.5 I will try to manage from there. Many thanks for your help.

Best regards,

Will do....

...done.

I have also renamed "cofactors" "cof" for consistency with the rest of the 3-char tensor function names.

The updates are now in our 1.5.x git repository.

Thanks Henry.
