VTK API: Working with values inside the python shell
I have some problems with the VTK API. The problem is a value which I have calculated before in a python script. I want now to import and to work with it inside the python shell.
That is what I have done so far:
s_kero = 3.4 #dummy value, normally calculated in a python script
Calculator2 = Calculator()
Calculator2.AttributeMode = 'cell_data'
Calculator2.Function = 'a*s_kero' # a: value from the CFD simulation
Calculator2.ResultArrayName = 's_kerosene'
Of course this is not working.... Does anyone have a suggestion?
Thanks for your help.
I'm not sure I understand the problem.
Assuming you're using ParaView, the code seems to work, at least up to a point. On ParaView 3.14.1, these following commands worked for me:
thank you very much for your response. Yes, I am working with paraview. I need to do some modifications on the results stored in a vtk-file.
Because I want to display these results later in Paraview, I am working with the calculator. The problem is, that my value, s_kero (your 2), is a value, that comes from a complex python script. It is computed for every cell and the numbers are changing depending on the input values.
I do not want to translate the entire phyton script with calculators in paraview. It would be too much work... I hope to find a way to create an interface between the value from pyhton and paraview.
So I have the calculator function:
Calculator2.Function = 'p*s_kero' where s_kero is a value, calculated for every cell and corresponds every time to a different number.
Sorry about that, it was late and I was tired. Right now it also took some time to finally understand the problem.
But still, there are (at least) two possibilities, because I'm not 100% certain of what you need. So:
Thank you very much!! Actually I can use both of your suggestions!!
