Error when using custom Wfact or Wfact_t in SplitODEProblem

14

In order to use a custom `Wfact` or `Wfact_t` with a split ODE solver, one needs to specify a problem of the form `SplitODEProblem(ODEFunction(f_implicit!; Wfact_t = custom_wfact_t!), f_explicit!, u0, tspan,...

I am seeing the following unexpected behavior with Julia version 1.10.2: ``` julia> foo(x) = x.:($(1 + 2)) + 0 ERROR: syntax: invalid syntax "x.((1 + 2))" around REPL[1]:1 Stacktrace:...

Revamp and extend ClimaCore matrix data structures

1

This PR will add a proper API for "columnwise band matrix fields" and "block matrices of matrix fields" to ClimaCore, along with unit tests and documentation. This will vastly simplify...

## Purpose This PR reformulates the IMEX ARK timestepping scheme, as our previous version was not accounting for the inter-stage effects of DSS and residuals from Newton's method. The new...

The coefficient arrays `a_exp`, `b_exp`, `c_exp`, `a_imp`, `b_imp`, and `c_imp` in the `IMEXTableau` are all guaranteed to have the same element type `FT`, but this is not necessarily the same...

Add Progress Bar

## Purpose This PR adds progress bar callbacks to ClimaTimeSteppers.jl. ## Content The specific callbacks implemented here are `BasicProgressCallback` and `TerminalProgressCallback`. The first one is designed for use with non-overwritable...

# PULL REQUEST ## Purpose and Content This PR adds Rosenbrock methods to ClimaTimeSteppers. Some of these methods can work with limiters (depending on the method coefficients), but that requires...

Fix kinetic energy conservation with topography
