Create and Manage Datasets

Datasets are collections of one or more simulation results used for training or testing a model.

Note: Dataset creation times vary because each solver result/input deck must be processed separately.

The following files are supported for PhysicsAI:

Table 1. List of Supported Files
Supported Solvers	File Format
Abaqus	.odb
AcuSolve	.ensight .h3d
ANSYS	.rst .rth
CCM+	.ensight
Custom/user-generated	.ensight .unv .h3d
Fluent	.ensight
LS-DYNA	.d3plot .d3eigv
Marc	.t16
Nastran	.op2 .h5 .xdb
PAM-CRASH	.dsy
OptiStruct	.h3d .op2
Radioss	.h3d .anim
ultraFluidX	.ensight

The required files based on the inputs and outputs to be used are summarized in Table 2.

Note: In Table 2, thickness and/or material is only for supported decks. See Custom Inputs: Global Hook or Custom Inputs: Nodal Hook for a list of supported decks.
