Help me, please.
I created geometry (furnace atomic absorption analysis) in Gambit.
I started to make the grid and the error occurred: "ERROR: TG mesh domain failed with error code1
ERROR: Tetrahedral meshing has failed for volume.
This usually caused by problems in the face meshes.
check the skewness of your face meshes and make sure the
face mesh sizes are not too large in areas of small gaps."
I created a new geometry, but the error remained.
I created the face of the grid, but the construction of the volume error.
I am newbie. Please, what is my fault?
Thank you.

you are trying to mesh a volume on the fly, but you have small entities in your geometry.
If you don't set any size function or whatever, Gambit will try to mesh the volume with the parameters you gave (and will fail because of small feature).
Check in your geometry where are small features, and use size functions

I ask for each face mesh. And then the total volume. There is also a negative volume of error. How to use the size functions?

Thank you. Happened. I found a very small volume. I made a simple volume and the mtsh was created.
