Three scales: macro, meso and micro. Overall, this multiscale simulation involved approximately 361 million degrees of freedom and required 266,240 microscale finite element analyses per macroscopic iteration.

Different representative volume elements (RVEs) are used in the multiscale simulation Example 1 Three distinct areas at macro level, each with its own RVEs Example 2 At each macroscopic Gauss point, an RVE is randomly selected from a predefined set.

Saving history curves to disk - [ValuesManager]

Saving history curves to disk Introduction In this section, it will be shown how to write the evolution of given fields to disk, e.g. the contact force as function of time. This is done with what is called “result curves”. These curves are saved for each time step while $\lambda = \frac{l}{l_0}$$\epsilon = \lambda-1 = \frac{l}{l_0}-1$$\epsilon = 0.5*(\lambda^2-1) $$\epsilon = ln(\lambda)$$$\frac{\int f^{old}-f^{new}}{\int f^{new} }$$
