We don't have a function that does that right now, but it should be relatively
easy to add one. For example, in 2d, you'd have a function like this:
double
TriaAccessor::extent_in_direction (const unsigned int direction) const
{
switch (direction) {
case 0:
return std::max(this->line(0)->diameter(),
this->line(1)->diameter());
case 1:
return std::max(this->line(2)->diameter(),
this->line(3)->diameter());
default:
Assert (false, ExcIndexRange (direction, 0, 2));
}
3d would be similar. If you wanted to implement a function like this, we'd be
happy to add it to the library!
Best
