Saving project is different from what the project print

[PengzhuLin]

Hi Professor Jeff Gostick.
I am trying to save my project. However, the save result (vtk) is not same to the printed one. Do you know about

Here we use the basic example. https://openpnm.org/examples/tutorials/09_simulating_invasion.html. How can we save the InvasionPercolation (ip) results to vtk file which can be used in paraview or other visulization software?

I use op.io._vtk.project_to_vtk(ip.project, filename="test") , but it fails to save the results.

I use "print(ip)"
ip_01 : <openpnm.algorithms.InvasionPercolation at 0x25cfcae1950>

6 pore.trapped 1153

and I save vtk result by using
op.io._vtk.project_to_vtk(ip.project, filename="test")

Thank you very much!

We decided not to include the results of algorithms in the VTK output since this would really clutter up the results, so if you want to see the algorithm's output in paraview you need to do something like phase.update(alg) which will copy all the arrays on alg onto phase. Hope that helps.
