    Thank you Andreas and Martin,<br>
    That's what I decided to do, Andreas. I compute the number elements
    marked for coarsening and for refinement, then I sum them up.<br>
    If this is zero I stop the run. By this way, I'm sure that the grid
    has not been changed. I can't say the opposite, i.e. some of the
    elements have been marked for coarsening but the grid doesn't change
    because of grid internal rules.<br>
    It doesn't matter, it's good enough for me.<br>
    <br>
    Thanks again.<br>

        I'm afraid it is as Martin says, checking the return of preAdapt
        and adapt isn't<br>
        guaranteed to prove 'grid convergence'. Couldn't you simply
        check if you are<br>
        actually marking elements or not? Although: it is possible that
        you mark elements for<br>
        coarsening and nothing is done because the elements couldn't be
        removed.<br>
        Best<br>

          <div>Hi Martin,<br>
            I'm trying to get grid convergence, then I have to know if
            the grid doesn't change any more in order to stop the
            computation.<br>
            Then, if I ask for the results of preAdapt and adapt and
            they're both false, this means that the grid didn't change.
            Right?<br>
            What do you mean with:<br>
            <br>
            However, it is perfectly ok for the grid to always return
            true on preAdapt and adapt, as this will not have an impact
            on the correctness of the solution. This would, of course,
            degrade performance.
            <br>
            <br>
            Does, for example, ALU always return true on preAdapt and
            adapt??<br>
            Thanks again.<br>
            <br>
