Simulate electrical conductivity directly on CT scans of different materials using the Transport Phenomena Simulation Module for VGSTUDIO MAX.
Electrical conductivity measures a material's ability to allow the transport of an electric charge.
The Transport Phenomena Simulation Module for VGSTUDIO MAX:
The electrical conductivity module is based on following differential equations for stationary voltage and current density fields in a two-component material:
where Ω is the entire simulation domain and Ωₐ is the domain of component a (with a = 1, 2). It is assumed that Ω₁ and Ω₂ do not overlap and their union equals Ω. U is the electric potential (in volts), J is the current density, σₐ is the conductivity of component a, Δ is the Laplace operator, and grad is the gradient operator.
In experiment mode, the software performs a virtual experiment on the CT data of a structure. Use the experiment mode to simulate the transport of electrical charge through the structure from an inlet plane towards an outlet plane parallel to each other. Perpendicular to the inlet and outlet plane, you can define sealed or embedded boundary conditions. A voltage difference must be specified as driving quantity for the flow.
The results are provided as 2D and 3D visualizations of the current density field as well as the potential. Electrical flow directions can be visualized by streamlines in 2D and 3D:
The following additional results are provided in a table view:
The following results can be viewed as curve plots along the flow direction:
In tensor mode, the software calculates the intrinsic effective tensor-valued electrical conductivity. Calculate the electrical conductivity tensor either on the whole structure or for increments of the structure by using an integration mesh.
The software provides electrical conductivity tensor results as 2D and 3D visualizations.
In addition to the tensors' eigenvalues and eigenvectors, the components of the effective electrical conductivity tensor with respect to the simulation coordinate system are provided in a table view.
