A non-aqueous pigment dispersion includes a quinacridone pigment, a polymeric dispersant, and a dispersion synergist in a non-aqueous dispersion medium wherein the dispersion synergist is a quinacridone derivative substituted on one of the two nitrogen atoms of the quinacridone basic chromophore structure by a group including at least one carboxyl group or a salt thereof. The multi-agents are programmed to monitor and control at least one function of the modeled physical components. for various applications and purposes, such as anatomic support, and for aesthetic and functional connections also with other manufactured items. A CFD simulation of the blood flow is performed in the 3D vascular model based on a blood flow parameter for generating a virtual 2D angiography recording.
