Advanced users of FlowVision are certainly familiar with the trick of using a remote non-computational subdomain for 2D simulations that utilise grid adaptation. This non-obvious method is used to disable mesh adaptation along one coordinate direction, thus making sure there will be only one cell across the width of the computational space. Despite being complicated, the trick works and helps to minimize computational mesh in 2D simulation.

In the new release of FlowVision, the 2D-simulation option is built into the program interface. Now you can create a project with 2D adaptation in just one click. Furthermore, the creation of projects with a 2D-sector condition has become easier. 

You can try it! In this article we'll be talking about why it's so important to first perform a 2D calculation instead of directly jumping into a 3D one.

Welcome to the FlowVision users team! Before you start creating your first project, you need to download the distribution pack and prepare it for work. In this article, we will tell you how to do this, so you can begin simulation of your engineering tasks as quickly as possible.

Here are the steps that will help get you absolutely prepared to run local FlowVision simulations on PC:

Step 1: Download FlowVision and License Manager
Step 2: Install FlowVision and License Manager
Step 3: Register the license 
Step 4: Create Solver-Agent user
Step 5: Check the license settings

 For the first time in our blog - the whole article is devoted to the FVTerminal module! If you want to speed up and automate the start of your simulations, then you just need to get acquainted with its capabilities.

FVTerminal allows you to perform certain operations while bypassing FVPPP, and can also do other cool things:

  • start and stop calculation (on local and remote computers)
  • download the client part of the project form the server part data
  • delete projects permanently 
  • connect to the Solver via the Viewer
  • and most interesting of all - queue projects 

To solve a numerical task, it is necessary to discretize space and time. A time scale allows to find intermediate solutions based on the initial and boundary conditions. Gradually coming through the intermediate solutions, we get the final one, which we can use to achieve the goals: choosing the right paint for the rocket skin, calculating the flow rate of your favorite ketchup, or getting the optimal washing temperature for a cat.

The intervals at which software calculates a solution are commonly referred to as the time step. It can be constant or calculated for each iteration based on a certain criteria. It should be noted that the time step is different for each specific software and task.

How to specify it correctly - we will describe in this article.
