HI,
I am using Fluent and UDF to do my simulations. In my source term for energy equation, there is a time-dependet term df/dt along with other terms depending on space i.e. du/dx Gradient calculation in UDF is straight forward i.e. C_U_G(c,t)[0] and that is in space. what about time? is there any nice commands like that or do I have to do my own first/second-order approximations of the term by calling the scalar at previous/earlier time steps? Does anyone has something to share on this topic? Thank you |
