As the block body is regarded as a continuous and isotropic linear elastic body, its mechanical properties can be described by the basic differential equations of three-dimensional elastodynamics [20, 21], which are as follows:
The acceleration, velocity, and displacement of the block body nodes can be calculated by (20), where [f.sup.out.sub.i] includes the interface and contact forces.
The final list of valves for the adjuvant skid included 46 standard two way valves, 18 sterile access fabrications, two three-valve fabrications, six multi-port divert valves, and nine custom block body
Valve manufacturers similar to ourselves, are more dependent on CAD designed multiport block body
configurations in eliminating dead legs and meeting the demanding requirement of ASME BPE SD-3.11.1 System Design L/D ratio of 2:1.
