[Libmesh-users] Question about Newmark system

[Povolotskyi, M. <mpo...@pu...>]

Dear LibMesh developers,

there is an example transient_ex2/transient_ex2.C where a wave equation 
is solved.

Could you, please, tell me how to modify this example if I need to have 
force that explicitly depends on time?

Thank you,

Michael.
