Hello,<br>
<br>
I am working on adaptive moving mesh problems. Therefore, the petsc<br>
vector size is constantly changing. <br>
The way I am currently dealing with this change is destroy the petsc vector <br>
first with VecDestroy() and create a new vector with VecCreateGhost().<br>
But I think this is not a really efficient way. So I am wondering if there is<br>
any way to resize the existing PetscVector dynamically. <br>
<br>
Thank you for your time.<br>
<br>
Kind Regards,<br>
Shidi<br>
