I'm facing some problems to kill elements above a temperature treshold.

I'm using the following loop to implement a gaussian heat flux, which is alternatin in a circle:

The heat flux application is easy, but the element selection due to high temperature is not working at all.

the 'bfe' flag on the esel command is 'body force, element'. The next field after 'bfe' tells which body force to select for i.e. temp = applied temperature, hgen = heat generation rate etc. But these are applied loads, and not temperatures solved as degrees-of-freedom. There is an option to select elements by element table value; please see the MAPDL help on the esel command. But it should be something like: esel,r,etab,temperature,tmin,tmax,tol

Hi Mike thanks for the answer. I managed to achieve the solution, the /post1, finish and /solu commands have be been missing or were arranged incorrectly.
Now the script is working just as intended.

Best regards
