Change thickness

The default thickness is equal to the element size at grain boundaries (denoted $s_0$ if a size-gradient is applied). This value can be changed as follows:

mesh(G,'titanium.msh','Thickness',20)

Add surrounding medium

One may want to embed the ROI into a prismatic surrounding medium, for instance to evaluate the local behavior of the ROI when surrounded by an homogenized material.

The following command creates a surrounding box of size $dX\times dY\times dZ$ (the ROI is centered along the $X$ and $Y$ directions):

mesh(G,...,'Medium',[dX dY dZ]);

E.g.:

mesh(G,'titanium_medium.msh','elementSize',20,'medium',[2000 2000 200]);

The element size is increasing with increasing distance from the ROI. To set the element size at the borders of the medium, append the mediumElementSize name-value pair argument. E.g:

mesh(G,'titanium_medium2.msh','elementSize',20,'medium',[2000 2000 200],'mediumElementSize',180);
