I am working on a python code to reconstruct the 2d flow, knowing the continuous force density applied on the fluid (by deritative of the strain tensor), which as the form of the derivative a gaussian function :

Fy(x) = -2A x exp ( -A x**2)

The force density has only a y component and is invariant with respect to y axis, which match perfectly the shape of the experimental flow field. I known that i am supposed to use the convolution between Oseen tensor and the force density to have the flow, but the results don't make any sense. Basically my goal is to transform the vectorial field of force density into the flow field, which has the same shape.

If you have any clue, i will be grateful Thanks by advance
