Hello community members,
I'm currently working with a dynamic mesh problem, specifically layering. I'm using Ansys 2019 R3 and the Fluent solver. To analyse the mesh, I would like to make a plot of the number of cells/nodes along a line, with respect to time. What is the best approach to do this? Can I accomplish this in Fluent Results or in CFD-post?
Specifically, I'm following the tutorial below. I would like to plot the number of nodes along the axis, betweeen the stationary left wall and moving left wall.November 23, 2020 at 12:13 pmRobForum ModeratorI don't think you can directly. Indirectly have a look at the xy plot as that looks to generate a data point for each cell/facet on the line. nNovember 29, 2020 at 12:10 pmavasudevSubscriberHi Rob,nThanks for this advice. How do you see this happening in practice? nFor instance, I managed to created an animation of a xy plot containing 'x-coordinates of nodes' on the y axis. How does it look? - As time progresses, x-coordinate of the interface node increases, until a new node is created (based on the parameters controlling layering) and processes repeats.nIndeed this is a step forward from where I started - which is some quantitative way to visualize the dynamic mesh. So once again thanks for that.nBut do see some way of using report definitions?.Best,nAneeshnNovember 30, 2020 at 11:05 amRobForum ModeratorThere's the SUM option in reporting, and that looks to sum the facet values on a surface. You can also get the facet average of the same scalar. If you divide one by the other does that give the number of cells, or a close approximation? I'll leave you to see what happens on a post processing line as that's not technically part of the mesh: a flow boundary or interior edge is. nNovember 30, 2020 at 12:14 pmDrAmineAnsys EmployeeYou can track the number of the cells by using that Sum report option. You sum 1 over all cells and it will provide with the number of the cells for certain cergions. Same can be done with faces along surfaces.nNovember 30, 2020 at 12:14 pmDrAmineAnsys EmployeeI see that was mentioning the same way.nViewing 5 reply threads
