[FAQ]

First create the Remote Point and set Behavior as Beam. Then insert a command snippet under the remote point to get the node ID of the master node using rpnode=_npilot Or just type rpnode in the details where it says “Pilot Node APDL Name” Now insert another command snippet under the analysis. First using command select the pilot node and then attached nodes. Then set the temperature load on the beam nodes. The APDL commands are attached below: nsel,s,node,,rpnode esln esel,r,enam,,188 ! eliminate all but beam188 nsle *DIM,tempload,TABLE,2,1,1,TIME, ! Time values tempload(1,0,1) = 0. tempload(2,0,1) = 1. ! Load values tempload(1,1,1) = 22. ! should be environment temperature for 1st load step tempload(2,1,1) = 101. bf,all,temp,%tempload% allsel,all For the beams you can conveniently specify a material under Remote Point details. And the material will have the coefficients of thermal expansion. You’ll will have to guess a beam radius for each beam connection attached to remote point and reference entities, but this should not make a difference to the thermal expansion along the beam direction.
