Hi,<br>
<br>
For some small parts of the code, it is preferred to use integer <br>
instead. Btw, to force variable as integer, I can use int(aa). However, <br>
I tried to force variable as PetscInt using PetscInt(aa) but it can't work.<br>
<br>
Is there any way I can make it work?<br></blockquote><div><br></div><div>I think you just define a PetscInt variable and use assignment.</div><div><br></div><div> Matt</div><div> </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">
