The accepted bit appears only after the checked continuum refs agree. Exact arithmetic here means exact results for the stated model inputs; measured inputs still carry uncertainty and significant-figure limits.
highlighted = computed this step
Every required source ref is present
The audit carries strain, elastic stress, pressure force, viscous stress, flow rate, relaxation time, shared height, and shared modulus refs.

The accepted bit is source-ref checked
The accepted bit is 1 only because all source refs and shared values close.
