The modern manufacturing industry has to meet two different requirements that pull in opposite directions:

  1. Shortest time to market; and
  2. Cheapest design and production process.

In such a context, virtual tools are becoming more and more important. From big companies to freelance consultants, the shift from prototyping and real tests to virtual modeling and simulation is an unstoppable trend. Unfortunately, these simulation tools are typically expensive. For this reason, technology partnerships like the one between Onshape and CONSELF are going to play a game-changing role for companies of all sizes.

Let’s take a look at how CONSELF’s cloud simulation apps for Computational Fluid Dynamics (CFD) analysis are easily accessed through the Onshape App Store. CONSELF’s simulation apps focus on the following industry sectors:

  • CFD » GENERAL: General purpose fluid dynamics simulations
  • CFD » HVAC | Jet fans: Contaminant extraction and fire simulation
  • CFD » TURBO | SRF pumps: Incompressible rotating flows
  • CFD » OIL & GAS | Flow with particles: Dispersed solid particles and erosion estimation
  • CFD » OIL & GAS | Multiphase: Two non-miscible fluids simulation
  • MECH » STATIC | Linear Elastic: General purpose stress analysis

Using CONSELF’s Cloud Simulation Platforms

In the App Store, first select the CONSELF app and click on “Go to Connected Cloud Application.” Once you are inside the CONSELF Simulation Platform, you can import your geometry from Onshape and setup your analysis in just a few clicks. Here’s how:

  • First, create a new case. From the Simulation tab, choose the application and give your case a name:
  • When inside the new case, navigate to your Onshape Documents and click on the “Onshape Import” button:
  • In the new window, select the file you want to import. Then log in with your Onshape credentials, choose the CAD model you want to import, and click on the “Import” button:
  • Once the upload is finished, you will be able to see your CAD model in the right window inside CONSELF:

Simulation Setup

With your geometry imported, it is possible to complete the simulation setup in a few clicks. In this case, since we are dealing with an airplane model, we will simulate an external flow (air flowing toward the plane) by following these steps:

  1. Geometry: Define your domain boundaries that compose the virtual wind tunnel where the plane is placed.
  2. Meshing: Define the dimension of your computational grid that divides your surfaces and volumes in faces and cells respectively.
  3. CFD: Define your simulation boundary conditions to prescribe where the air enters and its velocity and pressure, how surfaces interact with it and their role in the simulation.

Results Analysis

As the simulation ends, you are able to analyze your results directly online with our integrated post processor. The images below show typical plots for this type of simulation: pressure distribution, velocity variation and wall shear stresses (a measure of friction on our plane). Many more insights can be obtained with the wide range of tools available online, giving you a very powerful instrument to analyze your product performances starting from a CAD model.

It is important to highlight that this entire process, from CAD modeling to CAE simulation, has happened completely within a web browser. There is nothing to download or install and powerful hardware is unnecessary. Onshape and CONSELF both have free plans that make you able to start your own modeling and simulation immediately.
