I'm struggling adding time-dependence from Piro to my simulator. I'm
currently trying to demonstrate Rythmos in a simple 2d parameter-less
example. I have a few questions/issues:
I am trying to set x_dot ( * inArgs.set_x_dot(x_dot_init);* , where
x_dot_init is an Epetra_Vector of initial conditions)
I am receiving the error:*
model = 'Piro::Epetra::RythmosSolver': Error, The argument arg =
IN_ARG_x_dot is not supported!*
However, in my ModelEvaluator in createInArgs() I have:
I need to set x_dot in order to incorporate derivatives in my evalModel
residual function calculation. Is this really not supported or am I doing
How will a DAE time-domain solution be returned? In a multivector? How
should I set up my outArgs to see this solution?
Does a simple Piro with Rythmos example exist or has anyone written their
As always, thanks for the help. If you would like, I can also share the
simple example that I am working on.
