Hi,
I wonder if someone can help me understand how to mesh the attached object in hex only please.
I'm using hypermesh 13.0
Thank you

I think best way is to manually split the solid to regular shapes and mesh (or use solid map)
it's pretty complicated. Also in solidmap the one volume option does not work
It's not simple to make Hexa-only mesh. That needs alot of technique & time.
But I think GDTech's team could do that, of course, via a commercial contract :-)
I have managed these so far but struggling to get the whole thing to mesh. Any suggestions please?
@Dilen,
Maybe you can try some other options like line drag, ends only, etc...
Sometimes I get error message:
Non-mappable(1) along-faces form 0 loops. need 1.
Any idea what this means?
I think your splits are not mappable
my strategy is like this (sorry it's not completed /emoticons/default_rolleyes.gif' title=':rolleyes:' />)
Thanks but I'm not sure what you did. Would you explain please?
Is it possible to create a mixture of penta and hex elements? How please?
From point of view of mapping method, if your starting 2D mesh is quad only you got hex only 3D mesh. If your starting is mixte mesh (quad+tria) you got mixte hexa-penta 3D mesh.
do you think I can you a morphing approach for this geometry to get hex mesh?
I dont think that morphing will yield desired output.By the way did you try with shrinkwrap.PFA Hm file with Shrink wrap hex mesh.
<?xml version="1.0" encoding="UTF-8"?>
I have hypermesh 13. Any chance you can import it to this version please?
PFA hm file for 13.0 version.
Did you do just a normal shrinkwrap without specifying features or did you do a surface quad mesh first then shrink wrap?
For shrinkwrap there is no need of surface mesh.Just select component & set solid elements with lesser jacobian.I tried with 5 mm element size with .3 jacobian. So its a few click meshing process.
Is there a better way I can do this so that I can get good element quality because my model will involve other parts in contact.
try tetra mesh, then shiftF6 split it into hexas
It's quite a quick way but the jacobians for all elements become negative. Any ways to fix this please?
If you like 'Splitting' method, you have to accept some 'not-so-good' quality.
I think your splits are not mappable my strategy is like this (sorry it's not completed /emoticons/default_rolleyes.gif' title=':rolleyes:' />)
Hello Tinh,
I am running into an issue hex meshing a muscle STL. I was wondering how you drew the outlines that separated the solid object into multiple sub-components which could then be meshed. In the example you provided, only one of these components is hex meshed and this looks like the process I need to follow to fix my problem. I am new to HyperMesh, so any advise you could provide would be of great help.
Thank you,
Jack
Because you are new to hypermesh, i suggest you join altair training courses
I dont know how it can be done, 3d work is not easy, just try and error
