Getting postprocessing data for all time steps of a transient analysis

Please login with a confirmed email address before reporting spam

Hello,

I am dealing with a transient analysis. I need to get the value of a certain parameter (e.g. von-mises stress) for all the nodes in all the time steps. For example, if I want to solve the problem for 1 second, about say 40 time steps will be used.

I am using "posteval" function in the following form at the end of my m-file, but it only gives the value of that parameter for one time step (the last time step, I guess).

VM=posteval(fem,'mises_ps');

Do you know how I should use this command to get the value of that parameter for all the times steps of the transient analysis?
Do I need to use another command?

Thanks a lot,
MAsoud

Got it!

VM=posteval(fem,'mises_ps','Solnum','all');

Hi

You have alo the way through the dump of a plot, if you need the data just as a text file, but be aware that for large arrays or multiple plots there are sometimes mixing up of the elements in V3.5a

In any case your way via matlab is also the one I would choose

Good luck
Ivar
