Hi all,
I am a quite new user of FreeCAD and I am trying to model phase transition using a temperature dependent specific heat as specified on the CalculiX website (https://www.feacluster.com/CalculiX/ccx ... de172.html) but cannot find a way to do so.
Does anyone know about such feature in FreeCAD?
Thanks
Romain

Hi and welcome to the forum!
I moved the post to the FEM section. It is probably sensible to update to 0.20 or 0.21 so that helping comments match your version of FreeCAD.

Re: Phase transition modelling
Isn't that a part of non linear materials? i kind of would expect that...
Re: Phase transition modelling
No, FEM MaterialMechanicalNonlinear is just for plasticity and there's no equivalent for thermal properties.
Re: Phase transition modelling
Thanks for your answer
So I should provide some sort of csv type file including temperature ans specific heat values which would replace the specific heat value inside the .inp file, is that right?
Re: Phase transition modelling
It's not necessary. Just define it like this:
Code: Select all
*Specific heat
value1, temperature1
value2, temperature2
value3, temperature3
...

Thank you, I just tried this out and it worked.NewJoker wrote: ↑Thu Aug 11, 2022 1:02 pm It's not necessary. Just define it like this:
