Displacement due to thermal expansion

Altair Forum User

Hello,

 

 

I want to perform a simulation under optistruct to see the displacement and the volume expansion due to temperature change, I do not know how to do I watched the tutorial 1100 but it did not help me, thank you

Hi @nourlil

In the model shared I see force but no temperature load?

 

Could you please confirm?

Yes, i have done first simulation with force to have stress and displacement but now i need to see displacement due only to thermal expansion i have disactivate force on load step and create temperature on surfaces but i get error on solver.

Can you share the error message?

 

It will be great if you share the model file as well. You can use the file dropbox link in my signature to share the files.

Hi @nourlil

 

Temperature loads are not created properly. Please refer to tutorial 1100 and try again /emoticons/default_smile.png' srcset='/emoticons/smile@2x.png 2x' title=':)' width='20'>

Thanks by following tuto step by step i get the following error :

 *** ERROR # 720 ***
 Invalid static SUBCASE that has no load or enforced displacement.
     subcase id = 1

 

it s due to load so i don't know how to fix my boudary condition please help.

Hi Nourlil,

 

What type of subcase are you using?

 

Make sure you have referenced a compatible load type with the subcase created.
