Hi Kunal,<br>
<br>
the error message tells you exactly what the problem is:<br>
<br>
<tt><font color="#cc0000">--> in line 12 you are using 3
dimensions but the variable <br>
seems to have only 2 dimensions.</font></tt><br>
<br>
You are using: <br>
<tt> u = a->U(0,:,:) but it seems to be u = a->U(:,:)</tt><tt><br>
</tt><tt> v = a->V(0,:,:) but it seems to be v =
a->V(:,:)</tt><br>
<br>
Do the following printVarSummary calls to see the number of <br>
dimensions of the variables:<br>
<font color="#000099"><tt> printVarSummary(a->U)</tt><tt><br>
</tt><tt> printVarSummary(a->U)</tt></font><br>
<br>
Bye,<br>
Karin<br>
