Problem Description
For this example, you will run commands inside directory 19.
An Inconel® 625 test geometry is constructed on top of an Inconel 625 cylindrical build plate, using generic laser powder bed fusion processing parameters. Both the part and build plate geometries are imported in the analysis through STL files, and both are automatically meshed within Netfabb Simulation.
The build plate STL is assigned using the *STLM card by setting the configuration id=2. The PRM number is not used so 1 is used as a dummy value. The Material is the same as the PRM file, so the Material ID=2. No homogenization is used for the build plate, so the Volume Fraction is set to 1. The *STLM card settings here then are:
*STLM
2, 1, 1, 1.0
Constant build plate heating at 120° C., enabled by the *PBLR card, is used to mitigate distortion. The mesh and support type is shown in Figure 1. As in previous examples, first a time incremental thermal analysis is performed to ascertain temperature history of the part through the manufacturing process and post-processing steps. A subsequent time incremental mechanical analysis is then completed to determine mechanical response.
