Is there a way to release all moments at the end of beam 188?


You could utilize a macro to create the new node and couples. A possible
macro could look like this.

! macro file named bmomrel
!
! macro to remove all moment transfers from a node of a beam 188
! or similar element
!
! arg1 is the element number
! arg2 is the node number to have the moment transfer removed
!
! assumptions - no nodes to be copied have non-zero rotation angles
! - only data validity check is that node is on element as I or J
!
*get,ar21,node,,num,maxd
ar21=ar21+1 ! new node number
n,ar21,nx(arg2),ny(arg2),nz(arg2)
!
*if,arg2,eq,nelem(arg1,1),then
emod,arg1,-1,ar21
*elseif,arg2,eq,nelem(arg1,2)
emod,arg1,-2,ar21
*else
/com, ERROR Node entered is not a beam end node.
*endif
cp,next,ux,arg2,ar21
cp,next,uy,arg2,ar21
cp,next,uz,arg2,ar21
!


-----------------------

To use it on your model and assuming you want to operate on element number 6 at node number 15
and then repeat for the other elements with the corresponding node number. You may be able to
simplifiy it more based on your model.


*use,bmomrel,6,15
