Reply To: MAPDL convection load with variable film coefficient and bulk temperature

[Francesco Miccoli]

I can now see that something has changed, using:

*dim,bartz,TABLE,50,61,1,X,TEMP
*taxis,bartz(1),1,0.13,0.130976,0.131951,0.132927,0.133902,0.134878,...,0.185
*taxis,bartz(1),2,0,50,100,150,200,250,300,350,400,450,...,3000

and 

*dim,bulk,TABLE,50,1,1,X
*taxis,bulk(1),1,0.13,0.130976,0.131951,0.132927,0.133902,0.134878,...,0.185

I get the following result

Still there are some nodes that are not correctly interpolated, but I can't figure out why some are and some are not!
