• ### Re: How to define temporal BC in Expression Editor

Hi,
thanks for the answer. This should work, of course, as well as I can create second time serie according to the recorded temperatures on the known node, but what I would like to do, is set the Temperature BC on any node just using editor in transient mode. So the temperature on the node (111) is changing during the time. If I write: Current = T(111)@(Time) + 5, the temperature of my node is in the initial time really 5 K higher, but in next time steps this difference is not preserved. There is no change in simulation, if I write: Current = T(111)@(Time) + 5 or if i write: Current = T(111)@(0) + 5. So the question should probably be: can I define the Time as variable?
Thanks!
• ### How to define temporal BC in Expression Editor

Hi to all,
I would like to define Temperature BC at node in transient model. This temperature should be 5 K higher than the temperature at some other node.
For example: Node Nr. 111 lies inside an area, where is the GW temperature seasonally changing. At node of my interest, I would like to have temperature 5K higher, than at node Nr. 111 during the whole simulation period. In Expression Editor this...  Current = T(111)@(Time)  ... does not work.

Is there any way how to simple define this?
