I apply a temperature load of 40 degrees Celsius to all facets of a 0.6 meter long part. Manual calculation produces a linear expansion of 0.28 mm. Solidworks shows 0.11 mm (Reference temperature at zero strain: 0 degrees Celsius)

In the same way, large strains in the metal are obtained when heated at 40 degrees Celsius (about 700 kg / cm2), although nothing prevents the metal from expanding.

Such results can not be or I just can not understand the simple logic of solidworks
