[esp-r] Re: temperature

[Iwona]

Thank you for your answer 
I wanted to create laboratory conditions. 
Defining the environment, I chose the 'Prescribed static' and then constant temperature (0.0)and radiation (0.0) for all walls. 
Initially, decrease in temperature was rapid, and later it was slower, and about 1.5 months there has been a stabilization of the processes of heat transfer and equalization of outside and inside temperature.
I am just distrustful about this long time of temperature equalization and failure to take account some parameter or program function.

Thank you very much,

Regards,
I.Silva
