Flow Simulation automatically adapts during the calculation.
Adapting a grid means breaking up its cells so that their total number increases until a given resolution is reached. Next, go to the tab Mesh adaptation (fig. In the same window, open the tab Payment and choose Time step – Manually, equal to 1 second. 9), set the value Physical time, which pulled up here when we chose the parameter Nonstationarity in Project Wizard… This parameter means the time until which the calculation will be performed set it to 5 seconds. Right-click on the line Input data and choose Calculation control options (fig. Now, for our problem, let us establish the nonstationarity conditions. 6Ĭoncerning Computational domain (that is, the one in which the calculations will be carried out), we set it arbitrarily: either by arrows on the model, or by specifying the coordinates of the area (Fig. In the same window, you can set the speed using dependencies, table values or a formula. Here we indicate only the flow velocity along the Z-axis in the opposite direction: 5 m / s. 5Īnd finally in the window Project Wizard we set the initial conditions of the problem (Fig.
In the tab Liquids choose Water… Push the button Further and proceed to setting the conditions on the walls – we will leave these values by default. We will also select the condition Gravity – and be sure to check that the acceleration due to gravity is directed correctly. The values Total time and Time step we leave it by default, we can clarify these parameters later. Then we need to set the condition Nonstationarity, since we are considering a transient flow, that is, changing over time. First is the challenge External, that is, the stream flows around a solid body (balloon). Next, we set the conditions for the type of problem (Fig. We will leave the SI units by default, but change the Kelvin degrees to Celsius degrees (Fig. In our case, we will use the function Project Wizard… This function automatically creates a new project, allowing you to specify the name and configurations.
There are several ways to set task conditions.
“SOLIDWORKS School”… By link you will find a video where we learn to analyze flow with Flow Simulation. 2īefore continuing, let me remind you that if you prefer watching lessons over reading educational materials, welcome to our YouTube channel. By adding Flow Simulation module into the SOLIDWORKS interface, create New project, where you can specify the configuration of the model, if any, and rename the project (Fig.
