Hi all,
Can you tell me that how can i access the gradient components of a scalar variable in OpenFOAM ? I have a scalar variable theta. I have to find out the y-component of the gradient of theta. then I have to find out the x-component of the gradient of the resultant. See the attachment for more details |

... otherwise, if it is in a solver or utility coding then there is:
Code:
fvc::grad(theta) |
