Open 3rav opened 8 months ago

3rav commented 8 months ago

Error:

 *ERROR in checktemp: no final temperature
        defined in node

If I have inp with this combination, there is an error in version 2.21 (where in version 2.20 it is ok)

*INITIAL...

  1. STEP: no TEMPERATURE but null/CLOAD/*DLOAD
  2. STEP: *TEMPERATURE

But with, is OK for 2.21:

*INITIAL...

  1. STEP: *TEMPERATURE
  2. STEP: null/CLOAD/DLOAD
