Hello, I'm using the following command to create paraview file:

ops.recorder('PVD', 'filename', '-precision', 10, '-dT', 0.0, *['disp', 'vel', 'accel', 'incrDisp', 'reaction', 'pressure', 'unbalancedLoad', 'mass', 'eigen', 3])

note that you have to create a blank file with the same filename and a folder with the same filename or you will get errors.
If you want to output the 'eigen' you need to do a modal analysis first.
By the way i'm also interested in creating a script that creates .vtk file, because I want to see in paraview stresses on elements.
For now I just saved the location of integration point of each element but i need the output of stresses and than create the file

Hello, I use openseespy for my research,
I use it on my laptop, on some Python web based platform and now I’m trying to run it on my iPad.
I use a Jupiter app for code on Python and I tried to install openseespy and openseespymac, but with no success, or at least they got installed but I got the error message that says something like “openseespy is not compiled for iOS”.
So I would like to ask how to compile OpenSeesPy and if it is possible to compile it for iOS.
Thanks

Thanks, that did the magic

Hi everyone,
I'm trying to plot the animation of the deformed shape of my 2D structure, but I always got this error:

Code: Select all

  File "D:\Anaconda3\lib\site-packages\openseespy\postprocessing\Get_Rendering.py", line 819, in animate_deformedshape
    time, Disp = idbf._readNodeDispData(Model,LoadCase)

  File "D:\Anaconda3\lib\site-packages\openseespy\postprocessing\internal_database_functions.py", line 280, in _readNodeDispData
    Disp = np.transpose(np.loadtxt(NodeDispFile, dtype=float, delimiter=None, converters=None, unpack=True))

  File "D:\Anaconda3\lib\site-packages\numpy\lib\npyio.py", line 1139, in loadtxt
    for x in read_data(_loadtxt_chunksize):

  File "D:\Anaconda3\lib\site-packages\numpy\lib\npyio.py", line 1063, in read_data
    raise ValueError("Wrong number of columns at line %d"

ValueError: Wrong number of columns at line 405

I create the database with createODB before the main analysis with this command:

Code: Select all

opsplt.createODB('GA_modeling', 'push')

and after the analisys I use this one:

Code: Select all

ani = opsplt.animate_deformedshape(Model="GA_modeling", LoadCase="push", dt=0.01)

where the problem could be?

Gaetanocmr

mmmm, that's strange.
Are you using something like this for getting output?

Code: Select all

reactions('-dynamic', '-rayleight') 
nodeReaction(node, dof)
nodeDisp(node,dof)

if so, maybe you should check your model

Gaetanocmr

Did you set the recorder in your OpsPy model?
