<p class="MsoNormal">Hi everyone,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I created a ticket on the trac system, but I don’t know which is the preferred way (trac or mailing list) please advise. Here is my problem:<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoPlainText">I am trying to solve the jacobian of a residual function in my structured CFD solver. In my application, I have 5 dependent variables and roughly<o:p></o:p></p>
<p class="MsoPlainText">1700 independent variables. The number of non-zero values in the jacobian matrix is roughly 200, hence the usage of the sparse_jac driver.<o:p></o:p></p>
<p class="MsoPlainText"><o:p> </o:p></p>
<p class="MsoPlainText">The jacobian driver works perfectly fine, but I obtain inf's and nan's in the non-zeros values array. Note that the row and column index arrays are fine when compared to the entire matrix output of the jacobian driver. I tried changing
the option array without success.<o:p></o:p></p>
<p class="MsoPlainText"><o:p> </o:p></p>
<p class="MsoPlainText">I was using version 2.3.0 and recently upgraded to 4.3.1 with the same behavior. I am using colpack version 1.0.9.<o:p></o:p></p>
<p class="MsoPlainText"><o:p> </o:p></p>
<p class="MsoPlainText">Can you please help me with my problem?<o:p></o:p></p>
<p class="MsoPlainText">Thank you for your time,<o:p></o:p></p>
