WebAug 7, 2013 · The meeting quickly came to be known as “the FEniCS meeting” because the ice sheet model involved is designed using software called FEniCS (Finite Element Computational Software) that helps solve the equations that describe ice flow. It’s a powerful tool that played a significant role in how quickly the model was developed and …

Although Glimmer’s dynamical core was relatively basic, a higher-order dynamics scheme was under development.
WebAbstract Polycrystalline blocks of ice have been tested under compressive stresses in the range from 1 to 10 bars at temperatures from —13°C to the melting-point. Under these conditions ice creeps in a manner similar to that shown by metals at high temperatures; there is a transient creep component and also a continuing or quasi-viscous component. WebABSTRACT. A micropolar phase field fracture model is implemented in an open source library FEniCS. This implementation is based on the theoretical study in Suh, H.S., Sun, W., and O'Connor, D. (under review) in which the resultant phase field model exhibits the consistent micropolar size effect in both elastic and damage regions identifiable via …
