 June 10, 2014, 05:48 Temperature table as boundary condition #1 New Member   Join Date: Sep 2011 Posts: 16 Rep Power: 13 Hi, I currently want to implement a boundary condition for a wall where the temperature is dependent on its position on this wall. From another program I get a table for the temperature distribution along this wall. Can anyone tell me how to implement such a boundary condition? Thanks in advance for your effort. Regards Philipp Btw. I am using openFoam 2.3.0

I have never tried former patch, It seems bit difficult. I would suggest you to go for "groovyBC". (refer: http://openfoamwiki.net/index.php/Contrib/groovyBC) Use any of these as per your requirement. -- Best Luck!
