<p>Thanks Matt! That works perfectly now. I have another question regarding accessing the quadrature information.<br>
</p>
<p><br>
</p>
<p>When I use PetscFEGetQuadrature(), then PetscQuadratureView(), I see what I expect regarding point locations, weights.<br>
</p>
<p><br>
</p>
<p>However, when I try to use PetscQuadratureGetData() the pointers seem to point to random memory locations. <br>
</p>
<p><br>
</p>
<p>The exact line from my test problem is: call PetscQuadratureGetData(quad,q_<wbr>nc,q_dim,q_num,pq_points,pq_<wbr>weights,ierr);<br>
</p>
<p>where the pq_* are the pointers giving strange output. The q_nc, q_dim, and q_num are all giving what I would expect to see. </p>

<div>You are clearly the first Fortran user interested in this stuff ;) Handling of arrays in Fortran demands some more work</div>
<div>from us. I need to write a wrapper for that function. I will do it as soon as I can.</div>

<p>Hello,</p>
<p>I'm developing a finite element code in fortran 90. I recently updated my PETSc and am now getting the following error during compile/linking on an existing application:<br>

</p>
<p>I'm running Mac OS X Yosemite (10.10.5). I've created a "minimum working example" (attached) that re-creates the problem. It's basically just dm/impls/plex/examples/tu<wbr>torials/ex3f90, but tries to create a PetscFE object. Everything goes fine and the
DM looks like what is expected if PetscFECreateDefault is commented out. Any idea what am I missing?</p>

<div>Yes, I had not made a Fortran binding for this function. I will do it now.</div>

<div>I have merged it to the 'next' branch, and it will be in 'master' soon.</div>
