Error on grid generation for spheres nested inside block

I created a geometry by nesting two concentric spheres (1m and 50cm radius) in the center of a block (2m^2).



After selecting Grid mode, on grid generation (accepting the default size) the following error was displayed in a window:

Grid generation error.

This is the model file:
Sphere1mSphere50cmInBox2m.fea

Thinking the problem could be with how I constructed the "shell" with concentric solids, I then built another model identical to the first except the smaller sphere was subtracted from the larger, creating the shell explicitly.

On grid generation a similar (identical?) error was displayed:

Here is its model file:
Sphere1m_minus_Sphere50cmInBox2m.fea

Should I have adjusted the grid size from the default? Have I violated a limitation regarding object nesting?

Thanks ahead of time for looking into it,

I am currently reworking the geometry engine which will hopefully help with the decomposition and be available sometime next week.

This sounds great!

Good luck,

I retested both examples included in this post. Both generate grid with no error:

Sphere1m_minus_Sphere50cmInBox2m.fea:



Sphere1mSphere50cmInBox2m.fea:



Thanks for the upgrade!

In order to take advantage of the 1.12.4 build 1.87 upgrade, must I rebuild geometries built with upgraded engine?  

I gather that the grid generation process must be repeated, but I am asking about the creation of the model using the Geometry mode, correct?

-Kind regards,

I was about to post about a problem I was having meshing a complicated geometry when I noticed this thread. I updated to the latest version and it fixed my problem as well.

Thank you,
