"Collocation software based on a Runge-Kutta time integrator for 1-D Parabolic PDEs and Schrodinger type problems, with spatial and temporal error control" R. Wang, P. Keast, and P. Muir The BACOL software package, which employs high order methods in time and space to adaptively control spatial and temporal errors in a method-of-lines approach, has been shown to be significantly more efficient than existing codes for the accurate numerical solution of systems of parabolic PDEs in one space dimension. In BACOL, the collocation spatial discretization gives a system of differential-algebraic equations (DAEs) which is treated using the DAE solver DASSL. Since DASSL employs backward differentiation formulas (BDFs), each spatial remeshing requires an interpolation of previous solution values. In addition, for DAE systems whose Jacobians have eigenvalues on the imaginary axis, such as those arising from Schr\"{o}dinger problems, DASSL performs inefficiently since the higher order BDFs are not A-stable. In this paper, we describe a new software package, BACOLR, which addresses these issues by using RADAU5, a DAE solver based on an A-stable, (one-step) implicit Runge-Kutta method. Numerical results show that BACOLR is generally more efficient than BACOL on parabolic PDEs and substantially more efficient on Schrodinger problems.
