New to NGSolve and trying out a few of the example cases but looking at the method for outputting solutions to view in Paraview.
In particular, I was trying out the simple Poisson problem and trying to use the VTKOutput but not very successful. When I issue the following commands, it throws up a TypeError
vtk = VTKOutput(ma=mesh,coefs=[gfu],names=[“u”],filename=“poisson_solution”,subdivisions=3)
TypeError Traceback (most recent call last)
----> 1 vtk = VTKOutput(ma=mesh,coefs=[gfu],names=[“u”],filename=“poisson_solution”,subdivisions=3)
TypeError: init(): incompatible constructor arguments. The following argument types are supported:
1. ngsolve.comp.VTKOutput(ma: ngsolve.comp.Mesh, coefs: list = , names: list = , filename: str = ‘vtkout’, subdivision: int = 0, only_element: int = -1)
Invoked with: kwargs: ma=<ngsolve.comp.Mesh object at 0x1218c6590>, coefs=[<ngsolve.comp.GridFunction object at 0x1218cf860>], names=[‘u’], filename=‘poisson_solution’, subdivisions=3
I am assuming that I am not pulling the correct solution variable out but unclear as to how I should properly format the solution.
Any help would be appreciated.
