Inizialitation of Temperature at a point

ekhilore · July 7, 2011, 08:13

Dear all,

Is it possible to initialize the temperature in a certain point of the model, not just in a domain or boundary?

Thanks in advanced

Nodal data is what gets initialized, so you can use if() statements along with x,y,z coordinates so that only a single node gets an initial temperature, e.g. for the line of nodes at x=0.005[m]:
if(x>0[m], if(x<0.01[m],300[K],200[K]),200[K])
or you can use step() functions to do the same thing.

I got it with the if statement, thank you very much
