Abstract

We present mesh resolution studies for large-scale, convection-dominated mass transfer computations in modeling the growth of single crystals of potassium titanyl phosphate (KTP) from solution. These computations are performed using the stabilized, Galerkin/least-squares (GLS) finite element formulation. Results are compared from three different finite element meshes that have varying levels of refinement. Use of the stabilized finite element formulation with a coarse mesh for this system yields converged but inaccurate results, showing the importance of careful error assessment when stabilized methods are used for such problems.
