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 |
