Physics Modules

+SOLID, +FLOW and +LAPLACE

Representing a set of fully integrated modules for ScanIP, +SOLID, +FLOW and +LAPLACE calculate effective material properties from image data using Finite Element-based homogenisation techniques. Quick-semi-analytical estimates or simulations in a built-in FE solver can be used to compute properties for samples (CT, micro-CT, FIB-SEM...).

Calculate effective linear elastic properties in +SOLID, absolute permeability in +FLOW and electrical/thermal/molecular properties in +LAPLACE. Choose from a range of boundary conditions and visualise and export your results.

Overview of the Physics Modules


Modules are available separately or as a bundle.

  +SOLID Module +FLOW Module +LAPLACE Module
  Calculates the effective stiffness tensor and individual elastic moduli of material samples. Perform numerical homogenisation with a built-in FE solver or derive quick semi-analytical estimates from segmented images. Calculates the absolute permeability tensor of samples of porous materials. Numerical homogenisation is performed using a built-in Stokes solver. Calculates the effective properties of materials whose behaviour is governed by the Laplace equation, including electrical conductivity/permittivity, thermal conductivity and molecular diffusivity. Perform numerical homogenisation with a built-in FE solver or derive quick semi-analytical estimates from segmented images.

Physics Modules (+SOLID, +FLOW, +LAPLACE) Technical Data

The Physics modules are fully integrated within ScanIP. They are used to carry out finite element (FE) based homogenisation in order to calculate the effective stiffness (+SOLID), effective conductivity/permittivity/diffusivity (+LAPLACE) and absolute permeability (+FLOW) of samples.
