#knowember 08 💡 Nonlinear colormaps
www.aspirational.engineering

Abaqus has a reputation of the best nonlinear solver out there. I have recently noticed that apart from geometric, material and contact nonlinearity it can also handle... colormaps with nonlinear values range.
Let's imagine we want to plot a displacement field that has values between -10 mm and 100 mm. In this situation we could use a diverging palette, but with a default setup the colormap will not tell us where the change between positive and negative values occur. To be able to do it user needs to modify the colour range so that 0 value is linked to the 'transition' colour.
I found another application of the 'nonlinear' colormap. When we deal with materials that undergo plastic deformations we could modify the palette so that it highlights yielding regions. I liked this setting a lot!
