Quick edit panel for solid mesh?

Rahul_P1

Good evening,

I just created a dragged 3d mesh in a solid. Now i would like to edit the amount of nodes on the edge. It seems like this option is only realizable in Quick-Edit for 2D-meshes (By the way: sometimes the editing of density i not possible, why?). So how can i do it on a 3d mesh? And why i cant use all Subpanels from the panel 'edit element' to 1, 2 and 3D? For example i would like to combine elements, but this is just possible on a 2d-mesh, not 3d!

2. Question:
like you see in the following picture the red elements are 3d, the blue ones are 2d. To check connectivity of elements i usually use Tool-> edges or faces. Its obvious, that the red notes of the 3d mesh below does not match completely (different node counts) witch the 3d mesh in the upper solid. To get sure, such things do not happen, how can i check this connectivity?

HotSauce,

You can use macros to edit your hexa elements,

You need to download the script and then run this script from the downloaded location by going to file > run tcl tk from within HyperMesh. see http://www.altairuniversity.com/support-forum/?mingleforumaction=viewtopic&t=87
you will find this and other scripts in the altair script exchange, go to learning > script exchange from the altair university website or here http://www.altairhyperworks.com/Script-Exchange.aspx?%3ftop_nav_str=1

you will need to log in with your university mail id and login credentials you get after registering to the client centre.

search for the scripts by just entering hexa in the keyword section.

Solid meshing options in Solid map can be used to maintain connectivity between multiple solids.

You can create face elements on the solid elements of one of the solids (tool > faces) and then use these elements in elements to drag in solid map. or if your mapping from the other direction these will be your elements to match.

If you want to use the one volume option then you need to go to geometry > node edit > associate and associate the nodes to the surface of the unmeshed solid, one volume will conform to nodes associated to a surface of the solid selected for meshing.

thanks!

With reference to my 2nd question i have 2 surfaces that i meshed now (2d-mesh, see picture below)
Like you see mesh left and right doesnt fit with the node count. I just cant figure out where to identify these kind of gap, is there any option that i oversee?

HotSauce,

You still have to use tool edges, this will identify the edges where there are different node counts, as in the image below you see there are free edges in the top 2 surfaces with different node counts while the surface below has no free edge in between due to complete connectivity.

The mesh as in your image with different node counts should be avoided in the geometry editing phase, when you have two surfaces that are connected to each other you can identify/modify the three types of connectivity one surface has with the other, the three types are

free edge (red)
shared (green)
suppressed (blue)

to change the connected edge type you can use toggle edge in quick edit > toggle edge
With this lines selector highlighted, Left-click a free edge (red) to make it shared (green), or a shared edge to make it suppressed (blue).

meshing the surfaces when they have free edge will not result in any connectivity no matter what the setting is in automesh, meshing surfaces with shared edges will reflect the connectivity option you use in automesh, If you use redo connectivity then mesh in surrounding areas of the surface you are meshing now will automatically be changes so that there are no free edges/dissimilar node count.

you can see how connectivity options have an effect on the second surfaces with the green shared edge while the first with the red edge does not take connectivity into account and the third with suppresses behaves as one surface instead of two different surfaces so there is no connectivity problems there
