Hello,
I am using transient heat transfer and nodal heat sources. If I am using the load curve 0 (default, during which the load does not differ in time), the calculated temperatures are totally out the range. The heat source gives enormous negative temperatures (for instance expected is +10 C, I get -1000 C).
If I switch to load curve 1 which has a factor of 1 during all times (load still does not differ in time) I get the expected results.
Could you please consult what may be the problem?
Best regards,
Ignas
