Re: New changes for CG set type in 2.3.1-p7 ?



   Satish,

    Can you please check this? We should be able to
call KSPCGSetType() either before or afterwards. It could
be that KSPSetFromOptions_CG() wrongly resets to the default
value. I looked at the code and didn't see any wrong logic.
Probably it may be easiest to just run in the debugger and
check if it wrongly reset.

    Thanks

    Barry

I know where I did wrong now: the call below:

      call KSPCGSetType( ksp, KSP_CG_SYMMETRIC, ierr )
should have come _after_:

 call KSPSetFromOptions(ksp,ierr)

Otherwise it just goes with the default Hermitian even if I don't set the
switch to Hermitian.


You should be able to verify if the correct type is used with
'-ksp_view' option.

Thank you again
