Member Function/Subroutine Documentation

addindampingforces()

subroutine springroutinesmodule::addinspringforces::addindampingforces ( real(dp), dimension(:), intent(inout)  FD, real(dp), dimension(:), intent(inout)  RF, type(springtype), intent(in)  spring, type(samtype), intent(in)  sam, real(dp), intent(in)  alpha2, integer, intent(inout)  ierr  )

private

Assembles system force vector contributions from a spring element.

Parameters

	FD	System damping force vector
	RF	System reaction forces associated with constrained DOFs
[in]	spring	The spring element to calculate damping forces for
[in]	sam	Data for managing system matrix assembly
[in]	alpha2	Stiffness-proportional damping coefficient
[out]	ierr	Error flag

This subroutine calculates the damping force contributions to the system force vector from the spring element assuming Rayleigh damping, and adds them into the system vectors FD and RF.
