- Improved faceting support in quality metrics such as duplicate nodes, tilt, dihedral angle, and others, to create better topological and water-tight meshes for 3D InterOp translated models.
How the parameters such as the sweep angle ([LAMDA]), the dihedral angle, the taper ratio will affect the flight performance, how to set the upper and lower limits of these parameters are determined by using theoretical, numerical and experimental approaches along with the designers' experience.
With existing technology, however, the accuracy of the estimation of the dihedral angle (figure 1) parameter, which is necessary to calculate the degree of torsion of the bond, is quite low, resulting in the problem of low accuracy in the estimation of the affinity of the bond in the simulation.
Choose a point in the saddle-shaped weld; dihedral angle of the point on saddle weld is the angle between the cylinder's tangent plane through this point and the pipe's tangent plane.
[22, 25], for lower temperatures, that is, 125[degrees]C (as in our TMA lower temperature experiments), the dihedral angle becomes zero.
In the structure of BPI-P, the dihedral angle between the imidazole core and the adjacent phenyl ring is 41.9[degrees], while in the case of BPI-T, the dihedral angle between imidazole and the neighboring 'thienyl ring is 19.0[degrees].
The calculated dihedral angle of C9-C7-C17-C18 is -179.489[degrees].
When this technique is applied to another rigid system, where the dihedral angle are locked, but the system is non-planar, complications arise.
This results in the formation of a big, essential planar heterocyclic ring system with 4.349[degrees] and 5.217[degrees] dihedral angle between the newly formed ether ring and the two original coumarin rings, respectively.
Recently, the conformational change of PLP, especially the dihedral angle between the PLP pyridine ring and the Schiff-base linkage, was proposed to play an essential role in the transaldimination reaction in a bacterial L-serine hydratase (XometC) .
