Hi,

I'm attempting to use command blocks to run a dowhile loop during the solution step of a transient temperature analysis. When I try to get the temperature of a node on a top body I get the message for various nodes I've attempted.

 Requested data is not stored for node 9484.                            
  Line= *GET, TopNode, Node, 9484, BFE, TEMP                            
  The *GET command is ignored. 

What's the cause of this error?

I read that it may be a midside node, but none of the nodes I've tried so far seem to work.

What can I do to select a node in the area I'm selecting?

Hi, 

*get,,node,,BFE,TEMP --> is valid only for Static Structural (or Transient Structural), in /POST1. It gives basically the body temperatures input via "Thermal Condition" load or Imported Loads from upstream Thermal system.

To get the applied temperature constraints on a node i.e. via Boundary condition, we can use,

 *get,applied_temp,node,9484,d,temp

But, if the temperature you are looking for is node temperature after solving (i.e. at this particular node no temperature constraint is applied, but temperature is obtained as a result), we can use,  

*get,node_temp,node,9484,temp

or

node_temp = temp(9484)

But, please keep note that, the above two commands will not work for load step 1, since, when the solver reads these commands during load step 1, this step is not yet solved, hence there is no result yet. 

When these commands are read during the load step 2, they would basically give the result corresponding to load step 1. 

Hope this clarifies. 

Best regards,

Rohith

I was able to get the temperature of the nodes with the format you listed

*get,[insert variable name],node,[node id],temp

I was able to get the temperature of a node on the top body I listed as "TopNode" in the *get command.

*GET,TopNode,Node,6203,TEMP
