[CIG-SHORT] how to vary the cell size within the domain using the bias factor

[tu xiang]

Hello, Dr. Brad
I also increased the minimum cell size to 10 m, but it still cannot mesh the ellipsoid magma chamber surface (Trelis 16.0.3). In fact, I tried many values of the minimum cell size, from 3 m to 30 m, the trelis report the it cannot mesh the ellipsoid magma chamber surface.
I think, if I want to use an Exodus field, the volume should be mesh first. Such as:
${dx=15.0*m}
volume all size {dx}
volume all scheme tetmesh
mesh surface all
mesh volume all

I also tried many values of dx, but it cannot mesh the volume.

Then I am wandering how to vary the cell size within the domain using the bias factor?

I tried but did not work. This is very frustrating.

Hope you would help me!
Best regards,
Tu Xiang
