<p>hi, i am Xiang from University of Dundee.<br>
</p>
<p><br>
</p>
<p>Recently, i was confused by the tutorial of fem-1.4. In this tutorial, it does not use the classes of Matrix anyone and use Ellipticoperator instead of Laplaceoperator. Therefore, when i complied the tutorial of stokes, it showed that "<span style="font-family: Calibri, Arial, Helvetica, sans-serif; font-size: 16px; background-color: rgb(255, 255, 255);">error:
no type named ¡®BaseFunctionSetType¡¯". </span></p>
<p><span style="font-family: Calibri, Arial, Helvetica, sans-serif; font-size: 16px; background-color: rgb(255, 255, 255);"><br>
</span></p>
<p><span style="font-family: Calibri, Arial, Helvetica, sans-serif; font-size: 16px; background-color: rgb(255, 255, 255);">Then i did find that the tutorial of heat equation did not use the BaseFunctionSetType in fem-1.4. </span><br>
</p>
<p><span style="font-family: Calibri, Arial, Helvetica, sans-serif; font-size: 16px; background-color: rgb(255, 255, 255);"><br>
</span></p>
<p>Can you give me any suggestion?<br>
