OpenFOAM: chtMultiRegion - topoSet

[@MaximatumSupreme]

This was very educating. Thank You.

Hi. I am using snappyHex to create mesh out of my stl surfaces. How can i keep the all bodies (you know snappy removes)? I tried as Tobias showed but still removes the bodies. Thanks.

Hi, nice video, thank you. I have a question, can we add cells outside of blockMesh using toposet ? Or it must be inside blockMesh ?

[@chitranshatre3314]

Its a nice video and very helpful. Thanks for this. Could you please also explain how the bounding box dimensions are given? I don't understand only 2 points given in the box but the box has more number of points!!.

[@saeidhariri7182]

one the best videos that i saw. I would like to know how can trace or execute Particles ( as Particle Tracking ) in this box ! i ll be glad to know that .

What should be the name while using the invert command if multiple zones are already defined with different names, and I want to invert the last third zone?

Respected Sir, I want to use pisoFoam and laplacianFoam for fluid and solid region respectively. Can you please suggest the possible ways?

Hello, thanks for the video I have a conjugate heat transfer problem, few electronic components being cooled directly by a fluid (immersion method of cooling) and i am using OpenFoam for this. I am using toposet to identify different solid components inside the background mesh. Since some of the components are very thin (like a solder layer 0.1mm thick), i have to use a blockmesh with very high number of elements in each of the three axis. If the background mesh is not fine enough, toposet is unable to extract these thin solid components. I have to play with the backgroud blockmesh so as the toposet identifies all the solid cellZones successfully. Of course i can use snappy, but i do not think so i can get the same quality hexa mesh as given by blockMesh. Any idea how to make sure that toposet identifies a particular cellZone successfully without using hit and trial with background blockMesh? thanks

This was informative but you have not discussed action clear and delete; I am trying to understand the difference between actions clear and delete? I shall be grateful for guidance

Excellent job!

how to use topoSet for multiple STL files?

[@jccasava2035]

Thank you!

Amazing video, i understand the way of creating the cell zones, but what is not clear for me is how to determine the boxes. Could you please help me in this? thanks!

[@EnigmaticIguana]

to specify the box, you provide min and max values for x y and z. The openfoam wiki has a general formula, and the multifoam dam break case has a good example. If you'd like to see it in action, you can look at Joszef Nagy's multifoam tutorial Part One. Good luck!

[@EnigmaticIguana]

He also has an example here with "box (xmin ymin zmin) (xmax ymax zmax)".

Nice Video.. could you share me the syntax for reading stl file..!!

[@ing.nicola1706]

The same request .... in documentation I don't found nothing about STL

Hello.. nice video... Have you ever try to simulate propeller in OpenFOAM? I need your help. May you give me guide how to do propeller simulation in openFOAM? Thanks a lot Aldi

[@estaykylyshbek8347]

Same here. Have you already finished your project? Can you offer some help?

[@kasuora6233]

dude foam foam dude Plase, which real geometry is just like that in industry? Why anybody does this analysis??????????????? This topology is extremely unnecessary, I think.
