Thermal couple Structure

At this time I do the analysis with the structure and thermal.

 

And When I set the part with temperature in the model

 

It will have the error like that 

 

 There were 1519 error messages during input processing.
  The first message is repeated below:

  *** See next message about line 3823 from file: Thermal.fem
   'SPC            3       1            20.0'

  *** ERROR # 1310 *** in the input data:
  Invalid component number on SPC for GRID # 1.
 

 

My process is like that:

 

First constrain the full model nodes then set the D for temperature 20°C

 

<?xml version="1.0" encoding="UTF-8"?>

 

<?xml version="1.0" encoding="UTF-8"?>

 

 

I know we can first do the thermal then set sub, but can OpitStruct just run the structure with temperature?

 

Because my temperature is now for steady-state. 

 

<?xml version="1.0" encoding="UTF-8"?>
