'''Simulation modeling''' is the process of creating and analyzing a [[Digital prototyping|digital prototype]] of a physical model to predict its performance in the real world. Simulation modeling is used to help designers and engineers understand whether, under what conditions, and in which ways a part could fail and what loads it can withstand. Simulation modeling can also help predict fluid flow and heat transfer patterns.

==Uses of Simulation Modeling==

It analyses the approximate working conditions by applying the simulation software.

Simulation modeling allows designers and engineers to avoid repeated building of multiple physical prototypes to analyze designs for new or existing parts. Before creating the physical prototype, users can virtually investigate many digital prototypes. Using the technique, they can:

==Uses of Simulationsimulation Modelingmodeling==

Simulation modeling allows designers and engineers to avoid the repeated building of multiple physical prototypes to analyze designs for new or existing parts. Before creating the physical prototype, users can virtually investigate many digital prototypes. Using the technique, they can:

* Optimize geometry for weight and strength

* Select materials that meet weight, strength, and budget requirements

Line 12 ⟶ 13:

* Validate the likely safety and survival of a physical prototype before

==Typical Simulationsimulation Modelingmodeling Workflowworkflow==

Simulation modeling follows a process much like this:

# Use a 2D or [[3D CAD]] tool to develop a virtual model, also known as a digital prototype, to represent a design.

# Generate a 2D or 3D mesh for analysis calculations. Automatic algorithms can create finite element meshes, or users can create structured meshes to maintain control over element quality.

# Define [[finite element analysis]] data (loads, constraints, or materials) based on analysis type (thermal, structural, or fluid). Apply [[boundary conditions]] to the model to represent how the part will be restrained during use.

# Perform finite element analysis, review results, and make engineering judgments based on results.
