How to apply a bulk temperature on selected faces using ANSYS APDL codes

[GuillaumeT]

Good morning everyone,

I am currently trying to apply a uniform bulk temperature on the additionnal point of the SURF152 element but I do not succed to write the associate APDL code.

For this time I am working on a very simple case (A test case) - A simple cube (I attached pictures)
And there is my code.

1st: I created a nodal named selection (Called SNODES) on two surfaces in order to select nodes on these surfaces
2nd: I then asked to create SURF152 elements with the previously selected nodes
3rd: I then defined the element charateristics and finally select all these new surf152 elements.
4th: I applied the 500 °C to the surf152 elements

It appears that actually this code do not do nothing. Could you please help me to understand why ?

Yours faithfully

Guillaume THIRIET
