I am trying to simulate a time dependent heat transfer with time dependent heat sources.  The time dependent heat sources are at boundaries 36, 39, 45.



The simulation does not have any issues if the heat sources are fixed values, time independent, at these boundaries.

The simulation does not have any issues if the heat source at boundary 36 is time dependent but causes an error if any of the other boundaries (39, 45) have a time dependent source.

The error that the tool runs into is: "Deletion requires an existing variable"

Any ideas?

Thanks.
