Essential boundary condition on shell elements

[hnng]

With some valuable advise from this forum I have been able to offset the shell element and place it on a solid thermal element using.

ET,1,SHELL131

sectype,1,shell
SECDATA,0.05, 2, 0, 3
secoffset,bot
aatt,1,,1,,1

asel,s,loc,y,1
amesh,all

I am trying to apply essential boundary condition (temperature using D) to the top surface of the shell element. If I try to select the nodes on top surface of shell element using the nsel,s,loc,y,1.05 I do not see any nodes selected.

Can some help me in applying essential boundary condition at top shell surface?

Regards
Harry

Shells only have one node through the thickness. Select the appropriate nodes associated with the shell element and use the D command with the appropriate temperature DOF specified...TBOT (shell bottom), TTOP (shell top), etc.
