Hi, seems there are so many professional solidworks users! I am a new one and looking for some help.

I am doing a simulation about a beam in thermal expansion and have found a strange result.

 

study : static

material : alloy steel

fixtures: one end and all supports

temperature change : +30K

mesh: default

 

Model 1: a 500mm beam with five supports

The max. displacement is1.395e-001mm

Model 2: a 1000mm beam with 10 supports

The max. displacement is 1.404e-001mm

When I keep increase the length of beam to 5000mm with 50 supports, the max. displacement is similar to the model 1 and model 2. So, is it a reasonable result or something I have set wrong?
