GlobalStrainUserObject
Global Strain UserObject to provide Residual and diagonal Jacobian entry
Description
GlobalStrainUserObject
calculates the residual and the jacobian values corresponding to the integral of the stress tensor. In this case, the stress is generated due to global strain or any applied stress on the whole simulation domain.
ScalarKernel
GlobalStrain extracts the residual and jacobian values from this UserObject
.
