[Libmesh-users] question about Newmark system

[Michael P. <mpo...@pu...>]

Dear Libmesh developers/users,

I would like to solve the Newmark system, similar to your example:

https://github.com/libMesh/libmesh/blob/master/examples/transient/transient_ex2/transient_ex2.C


However, I need to have the force term that explicitly depends on time. 
Is it possible? If yes, how to achieve that, since the function 
assemble_wave(...) is called only once?

Thank you,

Michael.
