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.
