Assumed strain mode is the fastest simulation type available. It assumes that a constant, isotropic strain occurs at every location within a part as it is being built. The strain is equal to the Strain Scaling Factor multiplied by yield strength and divided by elastic modulus:

The Strain Scaling Factor (SSF) is an important factor quantifying the variables unique to each build scenario. It must be experimentally determined for each machine/material/strain/stress mode combination of interest. See the Additive Print and Science Calibration Guide.

Except indirectly through the use of the experimentally determined calibration factor (SSF), an Assumed Strain simulation does not use information about the machine or scan pattern.

See Set Up a Simulation - Assumed Strain for procedures.
