For three-dimensional solid simulations the Abaqus Interface for Moldflow translator makes a number of assumptions regarding the topology and properties of the data. These assumptions, listed below, ensure compatibility with the options available in the current release of Abaqus.
The Abaqus Interface for Moldflow translates the tetrahedral elements to an identical mesh of Abaqus C3D4 or C3D10 solid elements (see “Execution procedure for the Abaqus Interface for Moldflow,” Section 3.1, for more information).
Orthotropic material constants are in terms of material principal directions.
Material properties are constant for each element.
Orientations are defined in job-name_principalDirections.xml by giving vectors defining the local 1- and 2-directions.
Residual stresses computed by the WARP3D module of Moldflow in job-name_initStresses.xml are transformed from global coordinates to local material directions and used as initial stresses in Abaqus.
Loads and boundary conditions representing service loads must be added to the input file manually. For simulations using Moldflow Version MPI 6, the Abaqus input file created by the translator contains boundary conditions sufficient to remove rigid body modes from the model so that an analysis to solve for the response due to initial stresses can be performed easily.
