Doubt with SPC in heat transfer (Steady State)

Recommended Posts

Hello again, 

 

I'm doing a tutorial, OS1080, and i didn't understand why is used SPC, with all the boxes of degrees of freedom uncheked. What the SPC is used for? The subcase is (Heat Thansfer (Steady State).  

I found something about SPC on Reference Guide. The first figure bellow.The Step 4, from tutorial, tell me to make this SPC. 

 

Thanks!

Hi,

 

A structural constraint spc_struct is applied on the RBE2 element to fix the pipe on the ground. Two empty load collectors, spc_heat and heat_flux have been pre-created. In this section, the thermal boundary conditions and heat flux are applied on the model and saved in spc_heat and heat_flux, respectively.

 

Hope this helps :)

1. What do you mean by thermal Boundary condition in above post, is it temperature ?

2. Why SPC with all the boxes of degrees of freedom unchecked ? does it mean Zero temperature ?

 

Thank you in Advance
