Detailed Description

template<class TBASEMAT>
class TPZTransientMaterial< TBASEMAT >

Implements an implicit Euler time integrator. The Material Classes Material.

Weak statement is supposed to be Integral[(un+1 - un)/deltaT * v, Omega] + Bilinear Form = Linear Form This class implements only Integral[(un+1 - un)/deltaT * v, Omega]. Bilinear and linear form must be implemented in base class TBASEMAT.
