Dear All,

Good day, recently I have started working on the heat distribution analysis.

A heater is placed inside a container and we need to see the heat distribution in the container by conduction.

i) the problem is, all the sides, top and bottom walls are insulated ( no heat is transferring from insides to the surrounding)
ii) in the middle of the container a heater is placed, which is producing 375 C temperature.

iii) the container is tightly filled with solid material


my questions are:

i) in Ansys work bench, which solver i need to use?
ii) what are the boundary conditions need to be used?

Please give me some basic idea for the above problem

Thanks for your support,

Here's some guidance for your setup in Ansys Workbench:

**Solver:**

For this heat transfer problem involving conduction only, you should use the **Steady-State Thermal** solver within Ansys Workbench. This solver focuses on situations where the temperature doesn't change with time.

**Boundary Conditions:**

* **Insulated Walls:** Since all sides, top, and bottom are insulated, you'll need to define an **Adiabatic** boundary condition for these faces. This tells the solver that no heat transfer occurs across these surfaces.
* **Heater:** You have two options for the heater:
* **Surface Heat Flux:** If you know the heat generation rate per unit area of the heater, you can define a constant **Heat Flux** boundary condition on the heater surface. This injects heat into the model.
* **Temperature:** If you only know the final temperature of the heater (375°C), you can define a **Temperature** boundary condition on the heater surface. However, this might not be the most accurate approach if there's significant heat transfer resistance between the heater and the surrounding material.

**Material Properties:**

* You'll need to define the thermal conductivity of the solid material filling the container. This property determines how easily heat travels through the material. You can find this value in material property databases or from the material supplier.

**Additional Tips:**

* **Meshing:** A good mesh is crucial for accurate results. Use a finer mesh around the heater for better heat transfer capture.
* **Results:** After running the simulation, you can use Ansys Workbench to visualize the temperature distribution within the container. Look for features like "Temperature" plots or contours.

**Further Resources:**

**Remember:** This is a basic outline. Depending on the specific details of your model, you might need to adjust the approach. If you have further questions or encounter specific difficulties, feel free to ask!
