time dependend and parametric solution?

Please login with a confirmed email address before reporting spam

Hi,

is it possible to solve for parameters and time dependend at the same time?
I'd like to model a viscoelastic material and apply a pulsed force. How could I implement this?

Thanks in advance.
Sabine

Hi

I woul suggest that you take a look at setting the solver in transient mode and check the use of the the "Solve - parametric sweep" this will generate a series of files for each parametric step

Hi,

thanks. Yes, the idea sounds good.
But how can I access the data when I export the fem-structure to Matlab? (Unfortunately I didn't find anything about that in the documentation.)

And a further question: Did I understand it right, that if I use the parametric sweep, I will get the whole time analysed for each parameter step?

Then the single steps would be totally independed of the previous/next step, wouldn't it?
However I'd like to do the parameter - time combination, because I'd like to see the effect of the former parameter step to a new force pulse. Is this possible?

Regards, Sabine
