I need to solve a equation by using the UDS in FLUENT, the form is :
d(R)/dt=S where "d" is the partial derivative, S is the source term,and R is the variable I want to solve, that is, the diffusion and flux terms are zero. How do I define it by the UDF code ?If the variable is density, according to the UDF manual,I want to know if I can set the "phi" (in UDS transport equations ) to be 1. if not, how can I delete the density in the unsteady term ? Thanks Y.P. Chen |
