Outputting displacements at a vertex for every single time step

[dalek-caan11]

Hello,

I've just started using sfepy and I've managed to set up a wave propagation model. I have outputted data like von-Mises stress around 20 times in the analysis which is great but I really need to get out displacement for a single vertex (or node) for every time step in the analysis which is around 9000. It's impractical do write out data for every single time step. Is there a way to write out displacement like this to a text file?

Thanks in advance for the help and advice!

Hi Ruth,

you can use a step_hook function for that, see [1,2,3]. Let me know if you need more help.
