Re: I don't find information about this error

1) The error message is wrong. I fixed this in the dev tree.

2) 'fill' is the fill ratio for speculative allocation. It looks like
    you gave PETSC_DEFAULT which is invalid. You need to
    give a real number (the ratio of the final to initial allocation)
    so it should be > 1.0.


Ok. I write "1" and runs. You guessed, after I writed "PETSC_DEFAULT".... but, I don't know/understand the value of "fill". There is a default value for this parameter??? What is the best input???

thanks,
jordi

PD: the solution was easy but the message "Nonconforming object sizes!" confused me.

    Hello,

    I'm using Petsc 2.3.1 in Debian (updated by apt-get) and I don't find
    information in the web and in the troubleshooting section about this
    error message:

    Maybe you know what does it mean because I've tried a lot of thing in my
    code to solve this problem :-((( My Matrices have the same dimension.

    regards,\j
