Partition Imported Geometry

I'm trying to partition a geometry that I've imported from Solidworks. I've introduced a workplane and drawn a rectangle where I wish to split the geometry to obtain different domains. After this I tried converting the rectangle into the solid, however keep getting an error that says, "output object is empty".

Also can I refine a mesh within a single domain? The purpose behind partitioning the domains is to refine it without any hassle.

Would appreciate any help. I'm kind of new to this.

Hello Arjun,
If you can, use 4.4: we've introduced a Boolean Operation called "Partition" that lets you do what you want easily.

Hi Jeff,

I appreciate your help. Unfortunately I only have access to 4.3b. Any tricks you recommend in this?

Regards,

Arjun

Have you tried combining your geometry with various rectangular blocks (to separate it into the parts you want) using Boolean operations such as difference and intersection?

The partition function worked wonders.

I've been going through some literature on the COMSOL website regarding mesh quality. The write up mentions, "minimum mesh quality" as a good parameter to assess mesh quality. It also mentions that these parameters vary with respect to the different applications.

I'm currently working on a 3-D model that simulates microfluidic flow. I'm using an insanely fine mesh yet the minimum mesh quality is of the order e-4. I've ensured the growth-rate is limited to 1 but have the x-direction geometry scale set to 3. (the direction in which steep gradients occur)

Any ideas on which parameters might be a tell-tale sign of a good mesh for a micro-fluidic application?

Cheers
