poor calculation with temparturedependant specific heat
I am trying to simulate the melting process with the method of effective heat capacity, which requires FLUENT to solve energy equations with changing specific heat. I wrote a udf to specify the specific heat. However, it doesn't help. Temperature rising rate is far beyond what it should be.
Then I tried to work with the constant specific heat, and the result was more acceptable, but not precise enough.
Could anyone tell me what should I be aware of to improve the iteration stability and precision with temperaturedependent property?
Thank you so much!
