Modeling Thermal Convection Using Citcom 5 - Numerical Methods and Grid |
|
Citcom employs a multigrid finite element method that solves for velocity and pressure via a primitive variable formulations [e.g., Hughes, 1987]. It uses the stream-line upwind Petrov-Galekin (SUPG) for energy equation [e.g., Brooks, 1980]. Some of the implementation issues are discussed in Moresi and Solomatov [1995]. This version of code also includes some enhancements (full multigrid and consistent projection) that are discussed in Zhong et al. [2000]. Most of you as a user may not care that much about these issues, but if you do, you can always check up these references.
