I have achieved convergence of the model. I deleted all unmeshed instances, added an offset to shell to avoid overlap and increased the number of increments for the transient thermal analysis.
It worked with tie constraints as you said.
Thank you very much for your help.
I did it with tie constraints and it seems better.
Can you please run my code attached to this comment please?
- Does the results for the last increment shown on the odb make sense to you? Do you think that heat is flowing along shell thickness?
- Do you think that a finer mesh will help with...
hello again,
I made changes in the model. Basically I have defined the whole volume inside the shell as a solid of the same dimensions of the shell and I have assigned a bodyheat flux to the solid.
How do I assign thermal contact between shell faces and the solid? it is a surface to surface...
So that could be a new shell box between the already defined shell box and the solid element? Does it have to be in a specific form?
Thank you for your help.
Yes, that’s my problem. On how to model the medium between the two parts.
I’m really clueless about that, I searched for tutorials on how to do it but wasn’t able to find one.
Is it defined on the interactions module?
Thank you again for your help.
I’ll review the code for mesh elements.
Regarding connection, if I define a tie constraint between shell box and solid element would it become the solution to have heat flux along shell walls?
Thank you
Hello
I am new to ABAQUS and I have to do a thermal simulation script in Python to observe the heat flux between a solid element and a shell box. I defined this case with a bodyheatflux assigned to the solid element and a surface film condition assigned to both solid and shell elements to...
Hello
- Heat propagates through thermal diffusion and convection (radiation is not considered)
- Yes, there is air inside the box and that is my main doubt, how to simulate air inside the box in abaqus?
- Heat can be generated by two ways, either assigning an internal temperature or placing a...
I am modelling a thermal load applied on a shell box (6 shell faces closed as a 'shoe box') in ABAQUS and I have a few doubts on model conception.
Basically, the idea is to simulate heat coming from the inside of the box to the outside. So I have to assign an inner temperature to 'simulate' an...
