AdditiveFEAOperation.signalFileContents Property

Parent Object: AdditiveFEAOperation
Defined in namespace "adsk::cam" and the header file is <Cam/AdditiveFEA/AdditiveFEAOperation.h>

Description

Contents of the machine-readable simsignal file generated by the solver. Each line of the file is a JSON object. These signals are meant to be more stable than logFileContents(), but less human-readable.

Syntax

"additiveFEAOperation_var" is a variable referencing an AdditiveFEAOperation object.
# Get the value of the property.
propertyValue = additiveFEAOperation_var.signalFileContents
"additiveFEAOperation_var" Is a variable referencing an AdditiveFEAOperation Object.
#include <Cam/AdditiveFEA/AdditiveFEAOperation.h>

// Get the value of the property.
string propertyValue = additiveFEAOperation_var->signalFileContents();
"additiveFEAOperation_var" Is a variable referencing an AdditiveFEAOperation Object.
// Get the value of the property.
propertyValue = additiveFEAOperation_var.signalFileContents;

Property Value

This is a read only property whose value is a string.

Name Description
Additive MPBF FEA Process Simulation API Sample

Demonstrates how to automate an additive Metal Powder Bed Fusion (MPBF) thermo-mechanical process simulation using the Additive FEA API.

The script creates a new Fusion design containing a simple box body, switches to the MANUFACTURE workspace, and creates an Additive setup using the Autodesk Generic MPBF machine and the MPBF 60 micron print setting from Fusion's library.

It then constructs an FEA input deck with the AdditiveFEADeckBuilder, configuring a thermo-mechanical analysis (layers per element, coarsening generations, adaptivity, STL tolerance, ambient and final temperatures, build plate Z bounds and XY extension, convection, and an STL map). The deck is applied to a process simulation operation, the PRM file derived from the print settings is attached, and the simulation is run via generateToolpath. The script parses signalFileContents to confirm a successful finish, then builds a second deck and uses AdditiveFEAUtility.warpTriangleMesh to generate a warped triangle mesh from the simulation results.
