Porous material design

Structure/property optimization. How can MIST help?

Quantify essential geometrical characteristics

Quantify properties of the 3D structure that are essential for the material’s large scale behaviour. E.g., connectivity of a low porosity material, or anisotropy and heterogeneity of a high porosity material.

Correlate geometrical characteristics with material properties

The methods for 3D geometry characterization in Mist are chosen because they explain and predict material properties well. See the link below for how this applies to properties such as mass transport, electrical conductivity and heat transfer.

Get to know the material structure in detail through interactive 3D visualization

The properties of a porous material are determined by its 3D pore structure. To fully understand the material it is therefore necessary to understand the 3D structure. Get to know your material in detail by exploring the 3D structure interactively in Mist.

MIST features

3D geometry characterization methods

Connectivity

Explore the connectivity visually and quantitatively using methods based on connected components and distances through the pore network.

Bottleneck effects

Capture bottleneck effects caused by variations in pore size (constriction), or bottleneck effects caused by poorly connected pores (path-bottlenecks).

Pore shape

Quantify the morphology in 3D using pore size methods that capture pores’ sizes, shape and directionality.

Heterogeneity & anisotropy

Quantify heterogeneity and anisotropy statistically or explore it in 3D by interactively visualizing subsets of the material with specific properties.

Adaptations to different user profiles

For regular users

Accessible tutorials

Learn how to use and interpret the 3D geometry characterization methods in Mist through tutorials with detailed video instructions.

Easy-to-use interface

Mist comes with an easy-to-use graphical user interface. Streamline the workflow and compute the geometry characterization for multiple structures simultaneously, visualize settings in 3D, and interact with the characterization results in 3D to get to know the materials structure in detail.

For programming-oriented users

Run computations in batch-mode

The computation engine can be run separately from the user interface for more advanced customization.

Advanced post-processing

For advanced post-processing of 3D geometry characterization data from Mist, load the results into open-source 3D visualization software like Paraview or load the results into Matlab using scripts supplied here.
