I have set up a parametric study with fluent, so I am using the same mesh, and only changing one temperature parameter to see the results.
ANSYS 2019 R3 Improves the User Experience and Autonomous Vehicle Development
The problem is that every time parametric study changes the temperature and wants to run the simulation, it is kind of loading the mesh and setup file again and again. This process elongates the simulation time significantly. I found if I do that manually, it will be way shorter. My question is that if there is a way to prevent fluent from reloading the model and just adjusting the parameter and running the simulation?
You set up as normal from there. I will try that, I think in that case it will reread the case file and it might take a while again. I tried changing the parameters while fluent is open when I click on the refresh button on the top, it only refreshes the input parameters, which is fast. I think that would be great if the same way could be enabled in the automated parametric study.
Are you working with components? Under design parameter tab in AN hit update parameters and not full project. Thank you for your response, I am updating the design points not the entire project.
I am using the update design points. As shown below, for every design point, it is resetting the fluent not closing itloading mesh and case again and then updating the input parameters and running the simulation. You can enable store case under solution or setup cell first-time creatingvthevfluent component. Thus would result in Fluent just loading case file like ydual insteafing of reading mesh and applying settings.
I tried importing only case file, it still reloads the case file and changes the input the parameters every time wants to use new parameters. Could you please send a screenshot of that option?Openshift exam pattern
I know this is just a test model to work out how to use parameters but have you evaluated if those velocities of air would result in Turbulent flow vs the Laminar flow you selected?

Hello peteroznewman, I'm using the version Attached Files.January 25,Parametric Study. Join Date: Sep I am simulating an external flow. I know we can do parametric analysis of variables from Fluent but is it possible to do even from meshing or we have to do hard way of individual simulation for each values?
January 25, You can make a new geometry by just changing a few numbers in Gambit Journal file that you have made the first time. Fluent has also a Journal file for automizing tasks.

The main parts of gate valve are body, gate disc, bonnet, spindle, handwheel. The lift of gate disc decides the flow rate. The simulation of the flow inside the gate valve for different gate lift heights can be done separately, but would consume a lot of time in setting up the cases.
Here, the advantage of parametric study comes into play.Barrette viva i cereali 100g in hipp
We can setup a single case and then parametrize the lift value as input parameter and mass flow rate out of outlet to be output parameter. This will reduce the time required for manually setting up each case. So, the example of gate valve is taken to learn setting up the parametric case. The ends of the valve are extended to include the flow before and after the gate valve. On inlet side, the volume is extended by mm and on outlet side it is extended by mm.
These values of fluid volume extension are taken based on a previous simulation not posted here where it was observed that flow doesn't get disturbed if following dimensions are used.
This allows to decrease the element size without crossing the limit of number of elements. The gate valve lifts considered here are 10, 20, 30, 40, 50 mm. For each case, images of geometric volume, mesh, mesh quality, residuals, mass flow rate plot and animation of contour plot of velocity are given. Here, the mass flow rate is represented as negative because ANSYS treats mass flow of a fluid going out of fluid volume as negative. Setting up of parametric case is understood and the dependence of gate valve lift to outlet mass flow rate is studied.

I am doing a parametric study with ansys fluent. Is there any way? If you are working in the workbench and you want not only to get the output parameters updated but also to store the data of each design point you need to retain data.

Gate valve helps in regulate or shut the fluid flowing in a pipe. In present work, parametric study on flow through gate valve is performed by setting five design points of gate valve lift. Mass flow rate and area weighted average velocity is calculated at the outlet of pipe for all design points. Water is considered as fluid flowing through gate valve. Gate valve: Gate valve is a valve by lifting a barrier gate out of the path of the fluid. Gate valves require very little space along the pipe axis and hardly restrict the flow of fluid when the gate is fully opened.
The gate faces can be parallel but are most commonly wedge-shaped in order to be able to apply pressure on the sealing surface. Parametric study: A parametric study is the exploration of relationships and tradeoffs between different design parameters and the result from the simulation of those design parameters.
By using a parametric study, designers can assess the impact that changing certain parameters can have on the design on their performance goals. The more design options you analyze in a parametric study, the more information you will have available to you to understand the impacts of your design decisions. The three dimensional geometry of the gate valve is shown below. In order to analyse the effects of gate valve lift on fluid flow varaibles, a longer flow region pipe has to be considered to the inlet and outlet of gate valve.
This is done by using pull option in spaceclaim in order to extrude the inlet and outlet geometry to mm further. The extruded geometry is shown in the figure below. Now, gate valve lift has to be set as input parameter of the parametric study. This is done by lifting the gate valve by 10mm first design point using move option and selecting the component Gate and axis along which gate valve has to be lifted z-direction.
After lifting the gate valve to 10mm, option [P] is selected in order to set the gate valve lift as the parametric study input parameter.
Now the fluid volume is extracted from the geometry by using volume extract option in the spaceclaim. The extracted fluid volume is shown in the figure below.
In order to visualize the gat valve lift and understand the path of the fluid flow, sectional view is shown for all five design points. Face sizing: Face sizing is done to all the faces of the gate valve in order to capture the flow near gate valve accurately. Pressure-based solver: The pressure-based solver employs an algorithm which belongs to a general class of methods called the projection method. In the projection method, wherein the constraint of mass conservation continuity of the velocity field is achieved by solving a pressure or pressure correction equation.
The pressure equation is derived from the continuity and the momentum equations in such a way that the velocity field, corrected by the pressure, satisfies the continuity. Since the governing equations are nonlinear and coupled to one another, the solution process involves iterations wherein the entire set of governing equations is solved repeatedly until the solution converges.Autonomous vehicle development is dominating the engineering landscape.
The engineers developing these autonomous cars, planes, boats and drones are tasked to make the operation of these vehicles functionally safe. Proving this level of safety will require testing autonomous vehicles for billions of miles. That is not feasible or cost effective. However, engineers can use ANSYS simulation to test every aspect of these autonomous vehicles in a virtual environment — reducing development times and getting to market faster.
These improvements will enable engineers to quickly and efficiently drill down to near-optimal designs. The tool can automatically create a surface reconstruction from faceted geometry and STL files — effectively making smooth, watertight computer-aided design CAD models from a triangle-based geometry. Additive Prep also has a new feature that can separate supports from the part without separating the part form the baseplate. Finally, Additive Prep can now account for multiple support types in one simulation.
In addition, the HFSS distributed memory solver benefits from enhanced algorithms that increase computing speeds and reduce memory footprints.
Parametric study by just using Fluent
This feature will speed up the development of integrated circuit IC packages and printed circuit boards PCB. SCADE Vision finds edge cases where the autonomous vehicle system might have difficulty identifying certain objects in a traffic scenario.
Additionally, engineers can apply fault-tolerant meshes to nonconformal interfaces while performing a conjugate heat transfer simulation. Another user experience boost is that engineers can use the Fluent expression language with parameters, reports and monitors.
