Hello

I have another question. I want to apply a Heat Flux as boundary condition in a 1D-cartesian Problem. In the Users Guide I found that Natural and Load boundary conditions are synonymous. I found nothing about a boundary condition like "Point Natural" in 1D but if I apply these one there is no error message. The results are the same whether I use "Point Load" or "Point Natural", but not the results I expected.
Is there any difference for which reason I should prefer the "Point Load" in 1D Problems, because these ones are used in the Users Guide examples, or can I express a heat flux with both of them ?
Thank you for responses

The words NATURAL and LOAD are treated as identical.

Applying the "POINT" qualifier does not change this interpretation, so "POINT LOAD" and "POINT NATURAL" are identical as well.
