Sparse inversion for derivative of log determinant
Shengxin Zhu, Andrew J Wathen
Algorithms for Gaussian process, marginal likelihood methods or restricted maximum likelihood methods often require derivatives of log determinant terms. These log determinants are…
A constrained pressure-temperature residual (CPTR) method for non-isothermal multiphase flow in porous media
Thomas Roy, Tom B Jönsthövel, Christopher Lemon +1
For both isothermal and thermal petroleum reservoir simulation, the Constrained Pressure Residual (CPR) method is the industry-standard preconditioner. This method is a two-stage p…
A block preconditioner for non-isothermal flow in porous media
Thomas Roy, Tom B. Jönsthövel, Christopher Lemon +1
In petroleum reservoir simulation, the industry standard preconditioner, the constrained pressure residual method (CPR), is a two-stage process which involves solving a restricted…
