Overview of Powerful 2021

In this talk, the speaker provides an overview of Powerful 2021 and its features that are meant to streamline design for on-target real-world performance. The talk begins with a motivation for why these features are necessary.

Industry Drivers

Simulation needs to be connected and efficient to enable innovation in engineering design.

Transportation industry is moving towards electrical autonomous vehicles which require smarter, more connected designs.

Industrial equipment companies need to break silos and empower people to work together in order to become more agile and responsive to market needs.

Aircraft and defense industry is facing wrenching changes due to the global pandemic, requiring them to innovate, be cost-conscious, and think about decarbonization.

Features of Powerful 2021

Powerful 2021 has released several features that allow users to leverage simulation efficiently for complex time-consuming tools involving disconnected simulations.

Performance Expectations and Industrial Equipment as a Service

In this section, the speaker discusses how consumer expectations play a huge role in industrial equipment. They also talk about how equipment is bought as a service and the importance of ensuring that it can function in different conditions.

Consumer Expectations

Consumers expect vehicles to perform well under all conditions, be fuel-efficient, energy-efficient, and provide a comfortable experience.

Passenger confidence needs to be rebuilt by ensuring that airplanes are safe for passengers even if there are infectious people on board.

Performance expectations are high across every industry and are ultimately driven by end consumers who expect equipment to perform well under all conditions.

Industrial Equipment as a Service

Equipment is bought as a service rather than being purchased outright.

In order to maximize revenue, it's important that equipment functions well and meets requirements in many different conditions.

Enterprises face risks, so it's important to ensure that vehicles can handle any condition they may encounter.

Driving Costs Down with Powerflow

This section focuses on driving costs down with Powerflow. The speaker talks about the importance of early testing and simulation in meeting certification requirements while keeping costs low.

Meeting Certification Requirements

Regulations and certifications play a huge role in transportation, especially when it comes to meeting quality targets and regulations targets while keeping costs low.

Physical testing is too limited and too late to ensure certification. Simulation plays an important role in testing systems early.

Meeting certification requirements is critical for introducing new products into the market.

Driving Costs Down

As complexity and objectives increase, costs tend to go up. Powerflow aims to drive costs down by allowing for virtual testing and simulation.

The high fidelity of Powerflow allows for capabilities that will allow users to overcome the barrier of physical testing requiring physical testing.

Delta 2021 Enhancements

In this section, the speaker discusses the two strategic objectives of Delta 2021 enhancements. The first objective is to enforce connectivity to the 3D experience platform through Part Delta Power Buy. The second objective is to enhance powerful model build automation.

Automated Model Build Automation

In 2016, the target was set to achieve a model build turnaround time of one day.

Pardeta 2021 introduces key capabilities like automated gap detection convex wrap mesh boolean and templatable steps that made support of automation approach possible to achieve the goal of 24 hours turn around time.

The advanced common model build method developed by Simulia based on three different types of templates enables achieving four hours model build turnaround time with 3D experience platform.

Aero Model Build Automation

Three innovative approaches were developed toward a fully automated aerodynamic model build process.

Automated gap detection and field can now be achieved thanks to gap diagnostic capability semi-automated large gaps closure can now be performed using convex wrap capability and finally automated model build workflow can be achieved through new templates.

A video highlights the workflow and key capabilities for automating tessellation, mesh cleanup, dealing with holes, closing gaps between parts, and manually closing large gaps such as door handles using convex prep.

For brake cooling mesh preparation, standard templates can be used to automatically prepare powerful meshes but this time you can use scripting capabilities to automatically connect meshes to retain volumes and clean up four interferences.

Thermal Model Build Automation

Four enhancements were introduced in Pardeta 2021 for thermal model build automation, including scripting capabilities for iterative diagnostics cleanup, improved performance of all mesh editing operators when dealing with very large assemblies, thermal links generation scripting to make it easier to set up part therm simulation, and updated standard templates for semi-automated power therm mesh prep from existing power flow meshes.

A video highlights the workflow and key capabilities for brake cooling mesh preparation.

The speaker discusses Delta 2021 enhancements related to model build automation and provides examples of how these enhancements can be used in different scenarios. The focus is on the key capabilities that enable achieving faster turnaround times and automating various aspects of the model build process.

Preparing Models for Export

In this section, the speaker discusses how to prepare models for export and introduces a new feature in PowerDELTA 2021 that allows for automatic gap-based resolution.

Automatic Gap-Based Resolution

Automatic gap-based resolution is introduced as a counterpart to preparing assembly meshes for complex assemblies.

This feature automatically resolves gaps within complex vehicle assemblies, allowing users to specify how many voxels they want across a gap and apply coarser resolutions elsewhere.

The benefit of this feature is that it reduces overall model size and provides faster simulation results with practically no loss of accuracy.

An example is given where the model size has decreased dramatically without reducing accuracy much.

Run Management

In this section, the speaker discusses run management and how it can help solve issues with real-world simulations.

Run Templates

Run templates allow users to templatize complex workflows involving multiple simulations that are interdependent with each other.

These templates can be used to build up vehicle assembly simulations from geometry.

Run Templates and Management

In this section, the speaker discusses the benefits of using run templates and management to automate complex workflows. This includes reducing errors, saving time, and democratizing access to these workflows.

Benefits of Using Run Templates

Templatizing a complex workflow eliminates errors and saves time in moving files and launching workflows.

With run templates, simulation experts can create workflows that can be used by any engineer with minimal inputs.

Run templates allow for generating multiple runs, submitting them, monitoring them, and executing on very complex workflows.

Integration with Design Guides

Run management has been integrated with design guides to launch simulations for multiple designs and compare results.

The goal is to democratize access to these complex workflows so that anyone within an engineering organization can use them.

Examples of Using Process Automation

In this section, the speaker provides examples of using process automation for HVAC noise design and cabin thermal simulations.

HVAC Noise Design

Using run templates for HVAC noise design reduces turnaround time by 33% and eliminates 56 hours of wait time.

Automating the workflow reduces the risk of user error in a very complex process.

Cabin Thermal Simulations

Using run templates for cabin thermal simulations reduces waiting time between simulations by 16 to 48 hours.

Automating file copying reduces user errors and turnaround time by 40 to 70 percent.

Enabling Adaptive Coupling and Brake Duty Cycle

In this section, the speaker discusses how adaptive coupling can be used to run cabin comfort processes and brake duty cycle simulations. They explain that brake systems have multiple time scales in terms of fluid flow and thermal response, which can be streamlined using run management. The speaker also demonstrates a demo of setting vehicle speed as a design parameter for brake duty cycle simulation.

Enabling Adaptive Coupling

Power flow works with power thumb where the flow simulation is done in power flow and the thermal simulation with conduction, radiation, and human comfort is done in power thumb.

Using adaptive coupling, intervals between couplings are automatically computed based on the thermal time scale.

When temperature changes rapidly, the interval between couplings is reduced to run the flow simulation more frequently.

Brake Duty Cycle Simulation

Brakes design involves braking while going downhill for extended periods of time.

Multiple time scales are involved due to varying fluid flow and thermal inertia of brake assembly.

Run management can streamline setup by pointing to a run template and vehicle/brake assembly files.

Parameters such as geometry or vehicle speed can be parameterized for design studies.

A demo shows setting vehicle speed as a design variable for brake duty cycle simulation.

Streamlined Setup for Brake Duty Cycle Simulation

In this section, the speaker provides further details on how run management can streamline setup for brake duty cycle simulations. They explain that it replaces several hours of manual work with potential errors. The speaker also demonstrates how to select case files and launch simulations using Power Insight.

Streamlined Setup

Run management replaces several hours of manual work with potential errors.

Pointing to a run template and vehicle/brake assembly files can streamline setup.

Brake duty cycle simulations can be launched with a few clicks.

Launching Simulations

Case files containing input parameters such as heat generation rate and time series for vehicle speed can be selected.

Run templates in Power Insight, such as brake cooling and soiling, can be used to launch simulations.

A new run node is created once the simulation is launched.
