Hello,
I designed a model of the mid-ocean ridge, hoping to use the temperature field obtained from the model to compare the symmetry on both sides of the ridge. However, the temperature fields on both sides of the reference model I designed were not symmetrical, which made it very difficult for me to proceed with my subsequent research. The following images are the temperature values of the model’s temperature field that I extracted. As you can see, it is not symmetrical and the temperature on the right side is higher. Theoretically, the temperature fields on both sides of the mid-ocean ridge should be the same. What causes this discrepancy? If you can help me, I would be extremely grateful.
@sxj I’m not entirely sure what the numbers in the table represent, but assuming that you want us to compare the corresponding numbers in the two columns you highlighted in cyan, they are almost the same, to within about 1%. That’s pretty close. I bet that you would not have seen the difference if you had visualized the model.
You don’t show us how you created this data. There are many reasons why you might not get exactly symmetrical results. Among these are that your mesh is not symmetric around the ridge axis, or that your mesh is too coarse. What happens if you refine the mesh? What happens if you choose a domain and a mesh that is symmetric around the ridge axis?
Best
