<br>
I'd like to ask you a question about the grid.<br>
<br>
Suppose you are solving a problem on a given initial grid, and after a while some topological changes take place (coalescence, breakups, ...). For example, from one connected domain you get two, smaller disconnected ones.<br>
Suppose in addition that you have a software that removes tangles, returning the actual disconnected domain without self-intersections.<br>
<br>
I know that a grid can be neither created nor modified; so basically you can only have a reference to a grid, initialised by dereferencing a pointer to the the same grid type.<br>
So, if all the objects (function spaces, grid functions, ...) I have in my algorithm are defined over the initial one, is there a tricky way to continue my computations on the new disconnected domain?<br>
<br>
I mean, the new tangle-free grid is returned inside a time loop.<br>
I have initialised a new pointer to the same grid type by using a grid factory (since the new disconnected domain is returned through its connectivity, I insert vertices and elements by hand). However, I can't assign it to the reference to the old grid ...
Please tell me that there is a (dirty) workaround to continue the computations inside the time loop ........... otherwise I wouldn't know how to proceed without breaking the loop ........<br>
<br>
Cheers,<br>
