Test Case
A uniaxial bar composed of 0.2 µm ZnO powder stands freely without any constraints. The bar is loaded with temperature. Temperature increases linearly to 1000 K. At 750 K, the sintering process is activated, and the body starts to shrink. The temperature loading speed is 5°C/min during the sintering process. The relative density of the bar is obtained and compared against the reference.

Analysis Assumptions and Modeling Notes
The sintering material is defined by TB, SINT. The temperature is loaded in two steps, 750 K in the first step and from 750 K to 1000K in the second step. The first step is solved in one substep and the second step takes 30 substeps. The sintering process occurs in the second step, and its relative density is obtained using *GET in /POST1 and ESOL in /POST26. See the figure below.
