No node displacement from loadcase was found #16

Closed allenyoga closed 5 months ago

Hello,

I have a model in OpenSees and I wanted to plot the deformed shape using vfo. However, it seems like 'vfo' couldn't access the subfolder, 'loadcase', from OBD file on my computer: 

File "/Users/allenyogalee/anaconda3/envs/OpenSees/lib/python3.8/site-packages/vfo/vfo.py", line 609, in plot_deformedshape
    raise Exception(">>>> VFO ERROR: No node displacements from loadcase was found in "+model+"_ODB. Exiting 'plot_deformedshape()' now. <<<<")
Exception: >>>> VFO ERROR: No node displacements from loadcase was found in solar_panel_ODB. Exiting 'plot_deformedshape()' now. <<<<

There was no problem plotting modeshapes, so I don't think it's an access file authorization issue.

It's my computer's problem since the same code worked on my friend's computer.

It would be greatly appreciated if anyone could assist me with this issue.

Hi,

I kind of resolved the ‘access subfolder' issue above by only running the script 'create deformshape/animation' directly in the Python interactive shell:

`>>> import vfo.vfo as vfo

ani = vfo.animate_deformedshape(model="solar_panel_large",loadcase="wind",scale=5,speedup=1,contour="none",setview="3D",line_width=1,node_for_th=None,node_dof=3 ,gifname='new') Reading structure data from solar_panel_large_ODB. Reading loadcase 'wind' data from solar_panel_large_ODB. calculating maximum node deflections Creating animation gif/movie file. On-screen updating may seem choppy/slow. Please don't close the window. Movie/Gif file is saved.`

However, one other issue came up. The file wasn't saved since it's temporarily stored in the memory. If I 'exit()' the python shell the memory will be wiped out.

Is there a way to save it? I read through the source code of yours but hasn't figured out a way to use imageio.

Any help would be greatly appreciated. Thanks.

I am not sure why it wouldn't be saved. Did you check the folder? If it is a permission issue on your computer, then you'll have to figure it out.
