In a second step, the CBD was added through the AddBinder function of GrainGeo. This function detects NMC particles that are close to each other and joins them by adding a new phase between them in the shape of a concave meniscus. The shape of the resulting phase depends on the chosen contact angle. Tests with different contact angles revealed no significant difference in the results, therefore the default value of 0° was used. Additionally, the distribution of CBD was assumed to be isotropic, due to the low thickness considered and mild experimental drying rates. The volume of CBD added was selected to match the weight percentage of the components, while accounting for the material density and the different selected values of internal CBD porosity; e.g. when internal CBD porosity is set as 50 %, a real density of 1.8 g cm -3 is considered as 0.9 g cm -3 for the purposes of microstructure generation.
