Member Function Documentation

◆ Eval()

virtual real_t mfem::StrainEnergyDensityCoefficient::Eval ( ElementTransformation T,
const IntegrationPoint ip 
)
inlinevirtual

Evaluate the coefficient in the element described by T at the point ip.

Note
When this method is called, the caller must make sure that the IntegrationPoint associated with T is the same as ip. This can be achieved by calling T.SetIntPoint(&ip).

Implements mfem::Coefficient.
