gambit global geometric tolerance
 
i am modeling a micro geometry in the gambit.
when i want to mesh a face, gambit warns me as:
mesh size on face *** is smaller than geometric tolerance ....
i Know that the default global geometric tolerance of gambit is 1e-6 and the solution of this problem is to define it in a larger scale like mm.
but i can not change the scale, the geometry is so complicated and i cant really model it again.
i want to know if there is any way to change the global geometric tolerance in Gambit to some thing like 1e-7 ?
Help me please.
thank u.

Gambit has no unity.
If you are working in micro-m, then multiply all your geometry with factor 1e6.
For instance if you have a cylinder with radius 10 mu-m with an height of 100, thje create a cylinder 10x100.
You will need to scale your geometry in the solver, but later and independant to gambit
