Non-mappable solid problem.

Hi, I am trying to use the solid map feature to create a 3d mesh but there is an error that keeps showing up 'non-mappable(1):along-faces form 0 loops. need 1'. I have tried the HEX meshing but it still can't perform the mesh. I have googled but have not found answers to my issue. I don't know what else to do appreciate any help. I attached the hm. file.

Thank you.

Hello,
It looks like your model is symmetric, yes?

I had better luck splitting up.

You might also have some luck checking out some videos on our Altair How To channel on Youtube.

Thank you very much, I will try the method that you showed me.

I ve already tried the meshing by splitting but i faced this issue where near the defected area it is non-mappable. Is there a way to determine where to split the solid.

Not only would I partition the solids, but delete and only keep 1/4 of the model. You can then copy/mirror the elements.

Now more to the root of the issue, is mappable solids. And understanding first what they are.

Thank you for the help. I will first try "partition the solids, but delete and only keep 1/4 of the model and then copy/rotate the elements" as you have mentioned.
