POLYFLOW: Initialization of TEMPERATURE field from a CSV file

  In Multi-domain non-isothermal flow case or heat conduction calculation, when the TEMPERATURE field is initialized through a CSV file, temperature results do not match the expected distribution. Why is that? This may typically happen when the temperature has been initialized from a CSV file (Average temperature in Material Data menu) AND through a CSV file (specified in the menu for Numerical Parameters). The double definition creates the trouble. The easiest remedy here consists of assigning a single initialization value (Average temperature) in the menu of Material Data and to specify the initialization of the whole system through a CSV file in the menu of Numerical Parameters only. Whatever the value specified as average temperature, the CSV initialization receives a higher priority. The trouble does not appear for a single-domain calculation.
