An electrostatic finite element analysis of the electrospinning process of bilayer constructs using a parallel-plate collector

•Tailoring microfibrous constructs through electrospinning setup geometry.•The collector geometry of the electrospinning setup controls fiber orientation.•Aligned and randomly oriented fibers due to a parallel-plate collector.•Simulation of the electric field directionality explains fiber orientation.•Polymer deposition produces a local electric effect in electrospinning.
