<p>Hello, I have the following question about scaling imported convection loads in a transient thermal model in Ansys Mechanical. How can the ambient temperature values be scaled? For me, it doesn’t appear to be linear.<\/p><p>To illustrate this, I have set up an example model. If I import two loads that are applied sequentially, where the temperature in the second load step is exactly half of the first imported temperature, and then perform the same test again by only importing the first load step and scaling it by 0.5 for the second step (which should result in the same ambient temperature), I get different results.<\/p><p>However, when I do the same with HTC (Heat Transfer Coefficient), the scaled and imported values match. Does the scaling work differently for ambient temperature?<\/p><p> <\/p><p><\/p><p>For additional context, my model is a shell model with “temperature variation through thickness.” Thank you for your help.<\/p><p> <\/p><\/p>\n","protected":false},"template":"","class_list":["post-397108","topic","type-topic","status-publish","hentry","topic-tag-ansys-transient-thermal-2","topic-tag-imported-load","topic-tag-mechanical","topic-tag-scaling-1"],"aioseo_notices":[],"aioseo_head":"\n\t\t\n\t\n\t\n\t\n\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t
