I have a solved Laplace equation on a 3D geometry using finite element method. The potential values at each of the nodes are evaluated. I want a way to visualize the result, potential distribution across the volume of the cube.
I have tried the following libraries
a) matplotlib:: mplot3d
b) mayavi library
The FEM library like GetFEM++ writes the results as .pos file or .vtk file.
Can you please provide a way (with the help of a Python library) to store my data in .pos or .vtk format?
Looking forward to your reply.
Hi,
1. you need install the vtk library for your python distro,
2. follow simple code snippets to create unstructured mesh with both scalar/vector fields attached on nodal/element level (for example here: https://stackoverflow.com/questions/45665130/create-mesh-from-cells-and-points-in-paraview)
Hope it helps.
P.
