[Gmsh] Problem in meshing composite volume

[Wei-Ru Hsu]

Hi,

I am working on building a composite model. I want to build a liver model
which contains vessels, and
I write a geo file to do 3d meshing. After 3d meshing i think the model is
okay, and save it as inp file.
But I load inp file to Abaqus and do simulation, then error happened:The
area of 11673 elements
is zero, small, or negative. I have built a liver model without vessels and
do simulations in Abaqus before,
and nothing is wrong. I think it's because something wrong in building
composite model. Please help me
building composite model, thanks. The attached files are everything i used.


Best Regards,

Wei-Ru Hsu
