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
Today's topic is not how to obtain and install FlowVision license - this information can be found in our earlier blog articles or requested from our sales manager. Let's talk instead about when you would need a FlowVision license and when you can work without one. And also a little about licensing options and the error "No free licenses for this user".
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:
This functionality provides many opportunities for increasing accuracy of calculations while using less computational resources.
For your tasks, you can use:
- volume / surface adaptation;
- adaptation for curvature / sharp edges;
- adaptation by condition / to solution;
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.
You can use formulas in FlowVision to set any variable: from the gravity vector to the law of a moving body motion. All this became possible with the formula Editor. Using the formula Editor you may calculate composite functions, set the physical laws of variable changings and even set the level of adaptation for the calculation grid depending on the step number (and much more!).
In this article we will show how this functionality can significantly simplify the user's life.
Now it's easier to simulate sea waves in FlowVision!
You may set complex boundary conditions for the formation of natural gravitational waves using the formula editor. But these formulas are quite complex. Therefore, we used the computational engineering platform API and connected this module to FlowVision, so it became convinient to create user boundary conditions which generate waves.
For FlowVision 3.12.01 release we made a breakthrough in the development of processes in dispersed phases. As a result, it became possible to simulate the icing of surface. Today you can apply the both icing modes to your tasks - dry icing mode and wet one. What is the difference between these modes? How to simulate icing processes correctly? What results will be obtained in FlowVision? You will find all answers in this article.
A set of sensors is a measuring object which can be placed anywhere in the calculation domain.
Previously, to obtain a variable at a certain point of computational domain, it was necessary to create a small object with dimentions closed to the cell size and set a characteristic on this object. It became much more convenient with the help of sensors. You can simply select a point or even several points in space, create there the sensor set and receive data in one glo-file.
You have started a simulation of physical processes in Flow Vision by yourself, but the calculation always breaks down. Or the calculation runs, but the results do not correspond to physics. Is it familiar to you? Here is the quintessence of the experience from technical support and the training department staff. It`s a guide on what to do if your calculation breaks down.
To obtain the exact solution in numerical simulation, the reference values should be set correctly. Find out from this article how to set the reference values and how they affect the accuracy of the solution. We also examined two cases that our users usually face. Forewarned is forearmed.
Today we will talk about minimization of the computational mesh in a two-dimensional calculation. In general, FlowVision is a three-dimensional CFD software. But the 3D calculation becomes 2D if there is only one calculation cell in one direction. Unfortunately, two-dimensionality disappears when adaptation is enabled. User of FlowVision from JIHT figured out this issue.
