- variableThe name of the variable that this Kernel operates on
C++ Type:NonlinearVariableName
Description:The name of the variable that this Kernel operates on
InertialForce
Calculates the residual for the interial force () and the contribution of mass dependent Rayleigh damping and HHT time integration scheme ($\eta \cdot M \cdot ((1+\alpha)velq2-\alpha \cdot vel-old) $)
Description
This class computes the inertial force using a consistent mass matrix and also computes the mass proportional Rayleigh damping. More information about the residual calculation and usage can be found at Dynamics. Each InertialForce kernel calculates the force only along one coordinate direction. So, a separate InertialForce input block should be set up for each coordinate direction.
