You can find complete information about thermal analysis in ABAQUS. If you do not provide enough information about the different thermal studies, this package helps you understand this concept’s theory. This training package includes various workshops to teach in-depth.
One of the most rampant phenomena in the universe is heat transfer. Heat transfer can cause changes in mechanical characteristics. Heat transfer analysis can be divided into two types: consistent or transient. In this lesson, the settings and tips of these two analyses with examples are discussed.
Then, mechanical analyses under the effect of heat transfer analysis will be investigated. In some cases, these analyses (mechanical/ thermal) should become coupled simultaneously and, in some cases, can be performed consecutively. For each one, essential tips and items to detect problem type and usage method with related examples are presented. In the coupled process, hot forging analysis is presented as a workshop.
In some simulations, elements suffer from excessive distortion; In this case, you have to use the ALE technique. This technique is described entirely, and its difference with two methods, Lagrangian and Eulerian, is presented. This technique is used in the hot forging process; complete notes and steps to solve coupled include types of heat transfer, radiation, convection, conductivity, heat production caused by friction, heat production caused by plastic work, and dependency of elasticity and plasticity on heat is described.
In the second workshop, impact analysis is done. In this process, heat has a little time to distribute in the whole matter and, another type of heat transfer named adiabatic will be studied. This type of heat transfer and its applications are discussed thoroughly. The material in this process has used Johnson cook’s law, which mechanical characteristics depend on temperature and strain rate.
A full explanation of this model, along with the steps to implement on software, is described. Other matters in this example are investigating impact time, velocity changes according to the time chart of the bullet, the force, and the resultant torque graph of several elements and nodes.

In social media, users asked questions regarding Abaqus heat transfer issues, and we answered a few of them; you can see them below.
I. Comparing types of heat transfer analysis
Q: When comparing direct and sequential thermo-mechanical stress coupling in ABAQUS, I’m curious about which method gives the more accurate result and why? Please send any relevant theoretical literature if available.
A: Hi, That depends on your problem and analysis. To have accurate results in the shortest time possible, you should know which method is proper.

II. Surface film condition
Q: Dear all, In the 3D plate, we can apply the surface film condition along the thickness plane. However, if we transform it into a 2D plate, we won’t be able to apply the same along the thickness plane (XY plane).
In Abaqus, can we apply the surface film condition to a 2D face? Is there a way to do this through skin elements or some other method?
A: Hello, Generally, if your model is 2D, you can only apply surface film condition on edges. If you need to apply the surface film condition on a surface, you have to use a 3D model. the elements could be Shell or Solid. In your particular modeling, you have to use a 3D model and solid elements, and there are no other ways. I recommend you to refer to the following links. It’ll be worth it.

III. Heat transfer analysis in RC beam
Q: I’m using a heat transfer approach to analyze an RC beam that is operating at a high temperature. The entire surface is exposed to the same temperature. Additionally, I defined thermal interaction and amplitude.
The temperature at the nodes is constant.
Is there any issue in modeling?
A: Greetings,
I suggest checking your model again: material properties, step definition, element type, Amplitude, etc. It is highly possible you did something wrong.
Also, I recommend checking the link below. You will learn many things about thermal analysis in the ABAQUS. You won’t regret it.

IV. Heat transfer simulation
Q: Hi everybody,
I’m attempting to perform a heat simulation on a steel specimen. Proton irradiation and considerable heating are applied to the part. It’s fine to model this as (W/m) heating a specific section of my part. Are there any useful tutorials available to assist me? I’m not sure where to start when it comes to modeling heat transfer.
Cheers.
A: Hi,
If the proton irradiation equations are simple and do not a function of many variables. In that case, you can use the ABAQUS casual heat transfer analysis. Check the links below mate. You will learn heat transfer analysis with them.

But if the equations that cause the heat are complicated and have many variables, you have to use the DFLUX subroutine. Check the link below.
