Hello Barry,
I have seen you guys merged in main the minimum tolerance stuff.
After compiling that branch, I have tried to
call KSPSetMinimumIterations(this%ksp, this%minIter, ierr), but the
compiler cannot find the function.
I have included this module as standard practice:
#include "petsc/finc
Mega! This is gonna be useful for many people :)

Thanks Barry,
I have fixed the error. Indeed, It's odd it is working. Compiler magic I
guess!

This should not work. The argum
Hello Barry,
Mega! Thank you Berry much for providing me with a working example! I ended
up in writing this:
*call KSPConvergedDefault(ksp, n, rnorm, flag, PETSC_NULL_FUNCTION,

Note, you must call the default test on iteration 0. This is how it
determines the initial residual for relative residual tests etc.
I recommend not having the if () test at all. Instead, always call the
default convergence test first and then change the flag value it provides if
needed b
The code will not work as written because KSPConvergedDefault() requires a
context created with KSPConvergedDefaultCreate().
Here is a starting point for what you need, in main
integer*8 defaultctx
extern MyKSPConverged, KSPConvergedDefaultDestroy
KSPDefaultConvergedCreate(default

Yes. The other option is to pass along 'dummy'

Thanks,
Is this a reasonable thing to do if I want to replicate what KSP is doing
by default?

You are saying that no convergence context was passed in
Hi Matt,
h, what if I do:
KSPConvergedDefault(ksp, n, rnorm, flag, PETSC_NULL_FUNCTION, ierr)
That looks to behave OK, but I am not sure about what I am doing -.-
Cheers

Hello guys,
Today I am about to write a custom convergence test for KSP doing the
following job:
- if the number of ksp iterations is less than a given threshold, iterate
until that threshold is met
- if the number of ksp iterations is bigger than the threshold, use the
standard convergence check
