Sparse implicit solversChemical-kineticsEquationsModelsIn many applications of atmospheric transport-chemistry problems, a major task is the numerical integration of the stiff systems of ordinary differential equations describing the chemical transformations. This paper presents a comprehensive numerical comparison...
They differ in the way they solve a system of equations of the form Ax=b. Implicit vs. explicit solution is a different issue. What is commonly called explicit solution or explicit method, at least in solid mechanics, is really explicit solution with lumped mass formulation. This involves no...
This approach again limit memory use as the system is not NxN -where N is the number of cells - in place of (nxN)x(nxN) - where n is the number of equations; - compressible flows can be treated implicitly - as long as the flow physics you are interested allows for implicit ...

Standard explicit schemes for parabolic equations are not very convenient for computing practice due to the fact that they have strong restrictions on the time step. This stability restriction is avoided in some explicit schemes based on explicit-implicit splitting of the problem operator (Saul'yev ...
How can I prove the first order for the implicit scheme? (explicit is easy using a taylor-expansion around x). To get the derivative dy/dx|_(x+dx) (IMPLICIT), I have to do an explicit forward step to get y_(x+dx). Right?

We develop two efficient first- and second-order implicit-explicit (IMEX) methods for accurate time-integration of stiff/nonlinear fractional differential equations with fractional order α∈(0,1] and prove their convergence and linear stability properties. The developed methods are based on a linear...
Re: Implicit vs Explicit method #3 Jim Park Guest Posts: n/a "and so a matrix inversion needs to be performed." To nitpick a little, the matrix doesn't need to be inverted to solve the system for u(n+1); what is needed is to solve the system of simultaneous equations. This...
