Hi guys,
I am trying to calculate the gradient of an unstructed data set saved in
vtk format with the function in the following:
Somehow I am not able to access the PointData of the solution. The error
is always
* Grad_DMDu = dataAdp.PointData['Grad_DMDu']*
obj._dataset.Set(dataset.VTKObject)
TypeError: Set argument 1: method requires a VTK objec
So what am I doing wrong here?
Thanks in advance
