Feature block mesh edges
- adds a new, more natural way to specify block mesh arc edges using the arc origin that eliminates tedious and error-prone calculations. For example,
arc 0 1 origin (0 0 0);When the keyword is missing, this corresponds to the traditional means of specifying the arc via an additional point on the circumference (full backward compatibility). For example,
arc 0 1 (0.707 0.707 0);
