Fix: Include missing assertions in <code
- class="member">FEValuesBase::get_function_*</code>. This
- uncovers an error in <code
- class="member">DataOut<dim>::build_some_patches</code> that
- would have occured (at the latest) after the implementation of
- new <code class="class">FiniteElements</code> which shape
- values dependent on the geometry of the real cell.
+ class="member">FEValuesBase::get_function_*</code>. If an <code
+ class="class">ExcAccessToUninitializedField</code> is thrown
+ then probably an <code class="member">update_values</code> or
+ <code class="member">update_gradients</code> is missing in the
+ <code class="class">UpdateFlags</code> of an used <code
+ class="class">FEValues</code>. These assertions already
+ uncovered an error in <code
