Hello anyone

Can tell that why mesh of solid shell assembly is failing in Ansys mechanical especially solid part is failing.

Any ideas?

Green box is solid

Rest structure is shell element

First of all please update to latest version. 2019 is not supported.
Please check geometry in SpaceClaim.
Select geometry in structure tree --> Use right click --> Select Check Geometry. (Or Tools - Fault Detection in DM)
The geometry should be error free to proceed.
If geometry has any errors, please modify/recreate geometry at those places.
Please check if you can mesh that box independently. Please use different sizes.
Please check following videos

Hi Keyur
Thanks for reply...I alreday checked geometry in spaceclaim..my geometry is error free..as well as fluid domain also indpenedly meshed, it meshed it too.
I tried various sizes too of mesh..but still get error in solid domain.

Re tried it , again failing over solid element (fluid domain).
Error :The input model might not have a surface mesh that can be oriented and is suitable for tetrahedral meshing. Please check the input CAD model for errors.
