I&#8217;m a beginner in ANSYS and I&#8217;m currently using ANSYS Student.<\/p>\n<p>I want to determine how a frame will be affected by fire in Transient Thermal Analysis. The input parameters are temperature, convection, and radiation. Conduction is defined in the Engineering Materials. I used a linear mesh of 0.7m and the ambient temperature is 20C. However, the temperature seems to decline at certain parts. I observed these negative temperatures are on the structural members wherein there is no temperature parameter applied. I&#8217;ve tried to put &#8220;temperature&#8221; on the unexposed members but it still doesn&#8217;t work.
