Dear doctoral Chandra Sekhar Narra ,

I wanted to inform you that I have found several references that may answer your research question. Here are a few suggestions:

Gibby, R., Leibowitz, L., Kerrisk, J., & Clifton, D. (1974). Analytical expressions for enthalpy and heat capacity for uranium-- plutonium oxide. Journal of Nuclear Materials.

Bednarik, M., Červenka, M., Lotton, P., & Penelet, G. (2016). Behavior of plane waves propagating through a temperature-inhomogeneous region. Journal of Sound and Vibration.

Friedrich, H., & Levitus, S. (1972). An Approximation to the Equation of State for Sea Water, Suitable for Numerical Ocean Models. Journal of Physical Oceanography.

I recommend consulting these articles to gain relevant and in-depth insights into your research topic.

but, In Ansys Workbench, you can define a polynomial expression for temperature using the "User Defined Field" feature. Follow these steps:

1. Open your project in Ansys Workbench.

2. Go to the "Engineering Data" tab in the Project Schematic.

3. Right-click on "Engineering Data" and select "Insert > User Defined Field."

4. In the "User Defined Field" window, give a name to your field, e.g., "Temperature."

5. Under "Expression Type," select "Polynomial."

6. In the "Polynomial Coefficients" section, enter the coefficients of your polynomial expression for temperature. For example, if your polynomial is T = a + b*x + c*x^2, you would enter the values of a, b, and c.

7. Specify the variables for the polynomial. In this case, x can represent any independent variable you choose.

Dear M. Janane Allah,

Thank you very much for your recommendations and detailed answer.

Sorry to ask you, I have one more question, do you know how to make a simulation in 200 steps (I mean no. of steps is 200)in ANSYS Workbench?

my pleasure Chandra Sekhar Narra ,okay here is my proposal for this question. in Ansys Workbench, you can control the number of solution steps by adjusting the "Number of Substeps" or "Number of Steps" settings. Here's how you can set the simulation to have 200 steps:

*Open Ansys Workbench and navigate to the desired project.

* Double-click on the Solution branch in the Outline tree to access the Solution Settings.

* In the Solution Settings window, go to the "Analysis Settings" tab.

* Locate the "Number of Substeps" or "Number of Steps" option, depending on the version of Ansys you are using.

- If you have "Number of Substeps," set it to 200. This option divides the analysis into smaller substeps to achieve a more accurate solution.

- If you have "Number of Steps," set it to 200. This option specifies the total number of solution steps for the analysis.

* Adjust any other solution settings as per your requirements.

* Proceed with running the simulation as you normally would.

Dear M. Janane Allah,

Thank you very much for your answer.

Kind regards
